**Finding percent of a number worksheet :**

Worksheet on finding percent of a number is much useful to the students who would like to practice problems on percentages.

1. Use proportional reasoning to find 28% of 25.

2. Use multiplication to find 35% of 60.

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

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

**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.
