# Fractions and Rational Numbers – What is the Difference?

Most of us go through years of school math courses and still are confused about some basic things. For example: Why can not you divide by zero? Why is .999 … equal to 1, and not a bit less?

There are loads of these kinds of questions, that would not be a cause of frustration at all, if they were taught reasonably and clearly.

Unfortunately most of these things are supposed to be covered in elementary school, and most elementary school teachers do not have a good understanding of basic math concepts. Instead they are supposedly to teach just a collection of "skills."

One of the simplest concepts that is usually left inadequately explained is the difference between fractions and rational numbers. Let's see if we can clear it up now.

A fraction is a number that expresses part of a whole as a quotient of integers (where the denominator is not zero).

A rational number is a number that can be expressed as a quotient of integers (where the denominator is not zero), or as a repeating or terminating decimal. Every fraction fits the first part of that definition. Therefore, every fraction is a rational number.

But even though every fraction is a rational number, not every rational number is a fraction.

Why? Consider this:

Every integer (all the whole numbers, including zero, and their negatives ….- 3, -2, -1, 0, 1, 2, 3 …) is a rational number , because it can be expressed as a quotient of integers, as in the case of 4 = 8/2 or 1 = 3/3 or -3 = 3 / -1 and so on. So integers such as 4 or 1 can be expressed as the quotient of integers.

But an integer is not a fraction . 4 is an integer, but it is not a fraction. 4 is not expressed as the quotient of integers. The difference here is in the wording.

A fraction is a number that expresses part of a whole. An integer does not express a part. It only expresses a whole number.

A rational number is a number that can be expressed as a quotient of integers, or as part of a whole, but fraction is a number that is (must be) expressed as a quotient of integers, or as part of a whole – there is a difference. The difference is subtle, but it is real.

There are slightly different variations of the definition of a fraction, including, "A fraction is the ratio of two whole numbers, or to put it simply, one whole number divided by another whole number."

That definition also shows that an integer is not a fraction, because an integer is not a ratio. It can be expressed as a ratio, but it is not a ratio in itself; it can be divided by another whole number, but it i s not being divided.

In a nutshell, the fractions are a subset of the rational numbers. The rational numbers contain the integers, and fragments do not.

# Why Search Engine Optimization Is Necessary

When you search for a certain something on a search engine it opens up a number of pages containing possible answers for your search. These answers are your search results and the pages which contain these are the SERP or Search Engine Result Pages. Now, consider the many times that you have probably used a search engine, and the many results which each of these searches have raked up. If you think about it closely you will probably discover that out of all those million SERPs that you have opened up through your searches each time you have probably visited at the very most the first 3 pages of results, the rest you have ignored like they didn 't even exist.

As the owner of a website being thus ignored by visitors and sidelined by search engines has probably kept you up nights wondering exactly how you might better the position of your site. Well the answer is simple; through SEO.

SEO, or Search Engine Optimization refers to a process by means of which a website earns high ranking among the search results, gets a coveted place on the SERP and therey pulls in a large chunk of unique visitors.

Who needs SEO?

Websites can broadly be classified into 4 different types:

Personal sites

Corporate Sites

Sites providing information

E-commerce sites

As is obvious the first two types of websites can hold their own without using SEO. That is because they are target group is in itself a niche and it does not want or need audiences beyond that niche. However, that can not be said for the last two types of websites. If you build a site primarily to circulate information or for commercial use then you would definitely need unique visitors, these may be found only by means of good ranking on SERPs and therefore by means of SEO.

Another important consideration, while on the topic of content, is keywords. Your keywords are words or phrases which summarize or represent the main topic or subject of your site, when a search engine scans the body of your websites text it picks up these repeating words and match them with the words being searched if they match then you get a high ranking.

When selecting your keywords make sure you choose words which are most likely to be used by users searching for a site like yours or subjects covered by your site. After you have selected them sprinkle them abundantly within the text of your site. However be careful that you do not unnecessarily stuff them at inappropriate junctures cause that might attract criticism or even a penalty. Your keyword density per page can be anywhere between 5-15%, depending on of course how skillfully you may choose to repeat them. Make sure that you use your key words / phrases freely in the first two paragraphs of the text. Also, remember to include them in the concluding line of your text. But most importantly use them in your anchor text, certain Search Engines like Google put a lot of importance on the anchor text of your inbound links.

Judge for yourself

Here are the reasons we think optimization is a must, you decide for yourself.

More than 80% of net-users find websites by means of search engines.

90% of these users do not bother to check beyond the first 30 results.

75% of those using search engines intend to buy a product or service.

Professional SEO is twice as effective as all other internet marketing methods and 8 times more effective than banner advertisements.

# Recruitment Video is an Important Part of an Employment Branding Strategy

Video is the # 1 form of Internet communication and can be one of the most effective medium organization uses to build its employment brand. Recruitment videos posted on an organization's career site, distributed via podcasts and posted on YouTube and social networking sites can create excitation for the organization by allowing potential candidates to experience an organization's corporate culture, values, see multiple employees' passion for the organization and see what it's like to live and work in the organization. Google's recruitment video "An inside look at Google" as been viewed over a half million times on the Internet. Other organizations such as Yahoo, Microsoft, Cisco, IBM, JP Morgan, TiVo, the US Army and Home Depot have found great success using recruitment video. I recently read that studies have shown an effective recruitment video can increase passive candidate flow by up to 30%.

An organization's recruitment video is not a commercial and should not be scripted. The goal of the video is to give an inside look at the company and employees doing real work. A recruitment video should show real employees telling real stories about the organization. The video should also include a message from the CEO or an executive in the area of ​​the organization the video is targeted. The more real the video is the more effective it will be. An effective recruitment video should be 2 to 4 minutes in length. Remember you want a potential candidate to take action so make the video compelling and fun. When you create your recruitment video give potential candidates an avenue to respond by including a link to the organization's career site and if possible an e-mail address for candidates to forward their resume.

Recruitment video is a great way to increase employee referrals. Encourage employees to include a link to recruitment videos in their e-mail auto-signatures and individual FaceBook, LinkedIn, Ning, MySpace and other social networking site pages. We've discussed using viral marketing techniques to build employment branding. Ensure that those writing about the organization include a link to the organization's recruitment video.

Remember that your recruitment video is only as good as the employment site it directs potential candidates to. Potential candidates will visit an organization's employment site to confirm if what they hear about the organization is true, read detailed information about the organization, and submit their resume. The career site should clearly identify the organization's culture, values, vision, current job openings and benefit programs. The site should reflect an organization's brand and strengthen a candidate's desire to consider employment opportunities with the organization. Included on the site should be testimonials from employees that reinvigorate what potential candidates viewed in the video.
