## Finding percent of a number worksheet - Solution

Problem 1 :

Use proportional reasoning to find 28% of 25.

Solution :

Step 1 :

Write a proportion comparing the percent to the ratio of part to whole.

? / 25  =  28 /100

Notice that 25 is a factor of 100.

Step 2 :

Find the multiplication factor.

Since 25 x 4  =  100, find what number times 4 equals 28.

Step 3 :

Find the numerator.

7 / 25  =  28 /100

(Since 4 x 7 = 28,  28% of 25 = 7)

Hence, 28% of 25 is 7.

Problem 2 :

Use multiplication to find 35% of 60.

Solution :

Step 1 :

Write the percent as a fraction.

35% of 60  =  (35/100) of 60

Step 2 :

Always the word "of" is translated to "Multiplication" in Math.

Multiply :

35% of 60  =  (35/100) x 60

=  2100 / 100

=  21

Hence, 35% of 60 is 21

Since 25 x 4  =  100, find what number times 4 equals 28.

Step 3 :

Find the numerator.

7 / 25  =  28 /100

(Since 4 x 7 = 28,  28% of 25 = 7)

Hence, 28% of 25 is 7.

Problem 3 :

A sports store received a shipment of 400 baseball gloves. 30% were left-handed. How many left-handed gloves were in the shipment ?

Solution :

Step 1 :

Write the percent as a fraction.

30% of 400  =  (30/100) of 40

Step 2 :

Always the word "of" is translated to "Multiplication" in Math.

Multiply :

30% of 400  =  (30/100) x 400

=  12000 / 100

=  120

Hence, 120 left-handed gloves were in the shipment.

Problem 4 :

In a school of 800 students, 40% of the students are girls. Find the number of girls in the school.

Solution :

Step 1 :

Write a proportion comparing the percent to the ratio of part to whole.

? / 800  =  40 /100

Notice that 100 is a factor of 800.

Step 2 :

Find the multiplication factor.

? / 800  =  40 / 100

Since  800 ÷ 8  =  100, find what number divided by 8 equals 40.

Step 3 :

Find the numerator.

320 / 800  =   40 / 100

(Since 320 ÷ 4 = 40,  40% of 800 = 320)

Hence, the number of girls in the school is 320.
