What is fraction?

A fraction is the number obtained when one number (the numerator) is divided by another number (the denominator).

The fraction 4/5 means 4÷5

4/5

4 is a numerator

/ dividing line

5 is a denominator

Fraction are used to describe parts of qualities.

Example:

The fraction 2/5, 4/10, 6/15 all represent the same amount; they are equivalent fractions.

2/5 is the simplest form of 6/15, i.e 6/15 in its lowest terms is 2/5.

To add or subtract fractions, change them to equivalent fractions with a common denominator. For example

3/4 + 2/3 = 9/12 + 8/12 = 17/12

3/5 - 2/4 = 12/20 - 10/20 = 2/20 = 1/10

To multiply fractions, multiply numerator by numerator and denominator by denominator. For example

5/8 X 2/3 = 5x2/8x3 = 10/24 = 5/12 ( 5/12 is the simplest form of 10/24).

To divide by a fraction, multiply by the reciprocal of the fraction. For example,

35÷ 5/8 = 35/1 X 8/5 = 35x8/2x5 = 280/10 = 28
