Question

There are a total of 18 socks. If the ratio of purple socks to white socks is 2 to 4, how

many of them are white?

Answer 1

12

Explanation:

sum the parts of the ratio, 2 + 4 = 6 parts

Divide total number of socks by 6 to find the value of one part of the ratio.

18 ÷ 6 = 3 ← value of 1 part of the ratio, thus

4 parts = 4 × 3 = 12 ← number of white socks

Answer 2

12 of them

Explanation:

2:4

4:8

6:12
