Fractions

A fraction represents a part of a whole. That said, it consists of two numbers: the numerator (the top number) and the denominator (the bottom number). The numerator indicates how many parts of the whole are being considered, while the denominator indicates the total number of equal parts the whole is divided into.

As an example, in the fraction 1/2:

The numerator is 1.
The denominator is 2.

This fraction means that one part is being considered out of a total of two equal parts. And it works.

Decimals

A decimal is another way to represent fractions. Even so, the digits to the right of the decimal point represent fractions with denominators that are powers of 10 (10, 100, 1000, etc. Decimals are based on the base-10 number system, which means each digit in a decimal number represents a power of 10. ).

Here's one way to look at it: in the decimal 0.5:

The 5 is in the tenths place, meaning it represents 5/10.
