Question

if a:b=3:5 and b:c=10:13, find a:b:c.

Answer 1

Solution: If A : B = 3 : 5

B : C = 10 : 13

Multiplying the ratio A : B by 2, we get, A : B = 2 x 3 : 2 x 5 = 6 : 10

Therefore, we have A : B = 6 : 10

B : C = 10 : 13

----------------------------------

A : B : C = 6 : 10 : 13

Answer 2

a:b=3:5>>(1)

b:c=10:13, >>>(2)


so, LCM of both value of B=5 and 10


mutiply 1 by 2....


A:B:C=6:10:13
