Question

Which ratio can be used to form a proportion with the given ratio 8 to 12?

A:6 to 9
B:10 to 14
C:12 to 16
D:64 to 144

Answer 1

Answer = a - 6 to 9 8:12 reduces to 2:3 6:9 reduces to 2:3

Answer 2

we would first simplify all the proportions by treating them as fractions
8:12=2:3

6:9=2:3
10:14=5:7
12:16=3:4
64:144=4:9

obviously 8:12 and 6:9 are in proportion so the answer is A
