If a : b = 3 : 4 and b : c = 8 : 9, find a : b : c.

Question

KnowledgeBoat · Accepted Answer

Given: a : b = 3 : 4 b : c = 8 : 9 We make b, the same in both the ratios. Let us find L.C.M. of 4 and 8: L.C.M. = 2 x 2 x 2 = 8 So, we make b equal to 8 in each case. Now, multiply the first ratio by 2: In second ratio b has 8 in denominator already, so keep it as it is. b : c = 8 : 9 ∴ a : b : c = 6 : 8 : 9
