Question

if a:b=5:8 b:c=3:2 then find a:c​

Answer 1

Let us solve this equation quickly for you.

A : B = 2 : 5 => 5A = 2B → Eq. 1

B : C = 3 : 1 => 3C = B → Eq. 2

Now divide Eq.1 by Eq. 2 for A : C

=> 5A/3C = 2B/B

=> 5A/3C = 2

=> A/C = (2*3)/5

=> A/C = 6/5.

Therefore A : C is 6 : 5.

Answer 2

If a:b =5:8 and b:c = 3:2

Then

A=5 and C=2

Therefore,a:c=5:2
