Question

Anita brings 6 dolls to her grandma's house. These dolls represent 20% of Anita's doll collection, as shown in the diagram.

​

What is the total number of dolls in Anita's doll collection?
​

Answer 1

30 dolls

Explanation:

First, divide 100 by the percentage, which is 20, to get the number you need to multiply 6 by. 100/20 = 5. Then, multiply 6 by that number. 6*5 = 30. So, the total number of dolls in Anitas collection is 30.

To check, find 20% of 30 (and make sure it equals 6). To do so, convert 20% to a decimal, which is 0.2. 0.2*30 = 6. So, you have the correct answer.

Answer 2

Anita has 30 dolls

Explanation:

Let the number of dolls with Anita be x

20% of x = 6

`(20)/(100)*x=6\\\\(1)/(5)*x=6\\\\x=6*(5)/(1)\\\\x=30`

Anita has 30 dolls
