(a) 1 : 3 (b) 8 : 15 (c) 14 : 8 (d) 12 : 21

Answer 1

d option is the right answer

Answer 2

Answer-

We know that 4:7 = 4/7.

Lets check each and every option one by one.

(a) 1:3 = 1/3

(b) 8:15 = 8/15 = 2×2×2/3×5 = 8/15

(c) 14:8 = 14/8 = 2×7/2×2×2 = 7/4

(d) 12:21 = 12/21 = 2×2×3/3×7 = 2×2/7 = 4/7

Since all other options have different values and only option (d) is an equivalent ratio to 4:7,

●●●Correct answer is an option (d) that is 12:21
