## How to order numbers

Ordering numbers is an arrangement of the numbers in a sequence. The sequence of the numbers can be in ascending order or descending order. The ascending order is the arrangement of the numbers or alphabet from smallest values to biggest or greatest. The descending order is the arrangement of the numbers or alphabet from the greatest or biggest values to the smallest.

## How to calculate fractions

A fraction consists of two numbers that are written one above the other and are separated by a horizontal line. The number present above the line, is called the ‘numerator’ whereas the number present below the horizontal line, is the denominator.  A denominator represents the total number of equal parts into which something needs to be divided.

## Recurring decimals

A recurring decimal number are digits that do not end with zero but are repeated at the same periodic interval. A non-recurring decimal number are digits that do not end with zero, and they do not get repeated after any periodic interval.
