part

whole

=

percent

100

solution

The whole is 10.

The percent is 90%.

Let n represent the part.

Write a proportion to solve for n.

n

10

=

90

100

100n

=

90 · 10

100n

=

900

100n ÷ 100

=

900 ÷ 100

n

=

9

90% of 10 is 9.

You could also find the answer by writing and solving an equation:

part	=	percentage of whole

n	=	90% · 10

n	=	0.9 · 10

n	=	9

90% of 10 is 9.
