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

We can use a proportion to find out how many dolls Anita has in total:

6 dolls = 20% of Anita's doll collection

Let x be the total number of dolls Anita has:

6 = 0.2x

To solve for x, we can divide both sides by 0.2:

x = 6 ÷ 0.2

x = 30

So Anita has a total of 30 dolls.
