If A:B=7:9 and B:C =6:7 then A:C is​

Answer»

Given:-

  • A : B = 7:9
  • B : C = 6:7

To find :-

  • Value of A:C

Solution :-

Here A:B and B:C B ratio is same So, LCM of 9,6 is 18

A : B = 7: 9

We have to MULTIPLY with 2 in order to get B ratio same

A : B = (7:9)2

A : B = 14: 18

B : C = 6:7

We have to multiply with 4 in order to get B ratio is same

B : C =( 6:7) 3

B : C = 18 : 21

Now,

A: B : B :C = A:B:C

If you OBSERVE ratio of B is same

14 : 18: 21 = A:B:C

A : C = 14:21

A: C = 2 : 3

So, the value of A:C is 2:3
