Question

The Ratio of the length of Sam's string to that of Ryan's string is 2 : 7. If Ryan's string is 42 inches long, how long is Sam's string

Answer 1

12 inches

Explanation:

The 7 parts of the ratio represents Ryan's string of 42 inches.

Divide 42 inches by 7 to find the value of one part of the ratio.

42 inches ÷ 7 = 6 inches ← value of 1 part of the ratio, thus

2 × 6 = 12 inches ← length of Sam's string
