Answer:

Given

a:b=3:7

→ a:b = (3:7)

→ a/b = 3/7

multiplying and dividing both sides by 5 we get,

a/b×5/5 = 3/7 ×5/5

a/b = 15/35

→ a:b = 15:35 ____(1)

Given b:c = 5:8

Multiplying and dividing by 7 on both sides we get,

b/c × 7/7 = 5/8×7/7

b/c = 35/56

→ b:c = 35:56. ____(2)

From (1) & (2)

a:b:c = 15:35:56
