12 : 27 = 7 : X

(7/12) * 27 = X

X=15.75

2.

2/3 : 8 = 2/3 / 8

2/3 / 8 = 2/12

2/24 = 12

3.

4/5 / 1/6 = 4/5 * 6/1

4/5 * 6/1 = 24/5 or 4 4/5

4.

1/8 ft. / 2/7 ft.

1/8 ft * 7/2 ft.

7/16 ft

5.

2/3 to 8

is the same ratio if we multiply both 'sides' by 3/2

2/3 x 3/2 = 1

8 x 3/2 = 12

So, 1 to 12
