Question

The ratio of the length to the height of the American flag is 3:2. If the length of the American flag is 1.8 yards, what is the height?

Answer 1

27:10

1/8 equals 9/5

3/2*9/5=27/10

Answer 2

height = 1.2 yards

divide 1.8 by 3 to obtain 1 part of the ratio then multiply by 2 for height

$\frac{1.8}{3}$ = 0.6 ← 1 part

height = 2 parts = 2 × 0.6 = 1.2 yards
