Explanation:

Unitary method: Diving the number that u want to find out over the number that's already known :)

12 in = 20 ft

1 in = ? ft

`(20)/(12)` = 1.66666666667

1 in = 1.66666666667 ft

6 in = 1.66666666667 × 6 ft

6 in = 10 ft

(double check: 1.66666666667×12=20)

(Or: 12in ÷ 6in = 2 20ft ÷ 2 = 10ft)
