If A: B=3:8 and B: C=4:7 the value of A: C will be

If A: B=3:8 and B: C=4:7 the value of A: C will be 

To find A: C or A/C

After multiplying it we will get,

A=12

 B=32

C= 56

 ∴ 12: 32: 56

 If A: B=3:8 and B: C=4:7 the value of A: C will be

Now take 4 as a common factor you will get

3: 8:14

Since we have to find A: C

So, the answer will be

3:14

Or

3/14
