Knowing fraction definition and other related definitions, such as denominator, numerator, decimal, and decimal point is necessary for your kids’ success in math. Fraction is commonly defined as a number that names a part of a whole or a part of a group. In our previous lesson What is a Fraction? we explained this definition and gave some visual examples. We also gave advice on what to concentrate on when explaining fractions to your kids. There are some other definitions your child should know in order to be able to work with fractions successfully.
Numerator is the number above the bar in a fraction. This number tells how many equal parts are counted.
Denominator is the number below the bar in a fraction. This number tells how many equal parts there are in a whole or a group.
While numerator’s value “1″ stands for yellow part, denominator’s value “3″ stands for the number of all equal parts in total.
Decimals also name a part of a whole or a group just like fraction. However decimals look differently. The definition of decimal is a number with one or more digits to the right of a decimal point. Decimal point is a symbol that separates the ones and tenths in a decimal. Here is an example of decimal: 0.2. This could represent something like this:
If we were to use fractions instead of decimals we would write:
