Question

If A : B = 5 : 7 and B : C = 6 : 11 then A : B : C is ________​

Answer 1

Answer:

Step-by-step explanation:

A/B=5/7

LET x be common factor of given fraction

So, A=5x

B =7x

Now,

B/C=6/11

Let y be common factor of this fraction

So, B=6y

C=11y

B=7x = 6y

7x=6y

x=6y/7

A=5x=5*6y/7

=30y/7

B=6y

C=11y

A:B:C=30y/7:6y:11y

=30/7:6:11

=30:42:77
