Multiplying Fractions by Whole Numbers

To multiply a fraction by a whole number, write the whole number as a fraction with 1 as the denominator.

For example, let's find the product:

9 x
1
7

 

First, write 9 as a fraction.

 

9  =
9
1

 

9 x
1
7
=
9
1
x
1
7

 

To multiply fractions, multiply the numerators with each other and the denominators with each other.

9
1
x
1
7
=
9 x 1
1 x 7
=
9
7

 

Now,

9
7
 = 
1  2
7

 

So, the required product is
1  2
7
.
