Multiplying Fractions Chart


A fraction is a value that shows the number of equal parts taken of a whole quantity or unit. The denominator of a fraction is the number that shows how many equal parts are in the whole quantity. The numerator of a fraction is the number that shows how many equal parts of the, whose are taken.

The numerator and denominator are called the term of the fraction,

3 – (Numerator) / 4 – (Denominator)

Multiplying fraction chart methods:

Multiplying common fractions:

To multiply common fractions, multiply the numerator by the numerator and the denominator by the denominator. Reduce to lowest terms when possible.

Example:

(2 / 7 ) * (5 / 4 )

= (2*5)/(7*4)

= 10 / 28

= 5 / 14

Reduce lowest terms:

(2 / 6 ) * (3 / 4 )

= (3 * 2) / (6 * 4)

= 6 / 24

= 1 / 4

Multiplying fraction chart and a whole number:

To multiply a fraction and a whole number, follow these steps:

Change the whole number to a fraction by placing the whole number over one.
Then multiply the numerator by the numerator and the denominator by the denominator.
Reduce to lowest terms when possible.

Example:

18 x (4/8 )

= (18 * 4) / (1* 8)

= 72 / 8

= 9

Multiplying fractions chart and a mixed numbers:

To multiply mixed number, follow these steps:

Change the mixed numbers to improper fractions

Then multiply the numerator by the numerator and denominator by the denominator

Reduce to lowest terms when possible

Example:

(2 9/8 ) * (4 / 5 )

= (25 / 8 ) * (3 / 5 )

= (25 * 3) / (8 * 5)

= 75 / 40 = 1 35/40

Practice problem for multiplying fraction chart:
