7 yards : 9 feet = 21 ft : 9 ft = 7:3
7 to 3
1 yard = 3 feet9 yard / 7 feet = 27 feet / 7 feet = 27/7 = (3 and 6/7)
144 inches = 12 feet So 12:6 = 2:1 in its lowest terms
4 yards is 12 feet and so the ratio is 1 to 3
Simplification of RatiosExample 1Express the ratio 6 : 9 in its simplest form.Solution:Note: The ratio 2 : 3 is in its simplest form since the numbers 2 and 3 have no common factor.
2 feet:12 yards
36 inches = 3 feet (36/12). The ratio is therefore 4:3 (in lowest terms).
