Most of us are going through math courses and are still confused about some basic things. For example: Why can not you break zero? Why is .999 … equal to 1, not less?

There are many such questions that would not be a cause for frustration if they learned sensibly and clearly. 19659002] Unfortunately, most of these things are supposed to be covered in primary school, and most primary school teachers do not have a good understanding of mathematical concepts. Instead, they only have to teach a collection of "skills".

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

** is a number that expresses part of the whole as a part of numbers (where the denominator is not zero) **

A ** is a number that can be expressed as part of numbers (where the denominator is not zero), or as a decimal or recurring decimal. Each part corresponds to the first part of this definition. Therefore, each fraction is a rational number **

But although each fraction is a rational number, not every rational number is a small fraction

Why? Think about this:

** Each number (all integer numbers including zero and their negatives ….- 3, -2, -1, 3 …) is a rational number because it can be expressed as a part of numbers, as in the case of 4 = 8/2 or 1 = 3/3 or -3 = 3 / -1, n. Thus integers such as 4 or 1 can be expressed as part of numbers. But the number is not part **. 4 is an integer but is not a part. 4 is not expressed as a coefficient of numbers. The difference here is in the text

Fragment is a number that expresses part of the whole. The integer does not express part. * may be * expressed as part of numbers or as part of the whole, but the fraction is a number that * is * (must be) expressed as part of numbers or as part of the whole – difference. The difference is insignificant but real

There are a few different variants of the definition of a fraction, including: "Share is the ratio of two integers, or simply say, an integer divided by the other integer."

** This definition also indicates that an integer is not part because the number is not a ratio. He can be expressed as a ratio, but is not a ratio by itself; can be divided into another integer, but is not divided. In short, fractions are a subset of rational numbers. Rational numbers contain numbers and no fractions. **
