Question

If a ratio b=4 ratio 7 and b ratio c=5 ratio 3 then find a ratio b ratio c

Answer 1

Answer:

a:b = 4:7

b:c = 5:3

a/b= 4/7

b/c = 5/3

Here b us given twice

a:b = 4:7

b:c = 5:3

So in 4/7 multiply both the numerator and denominator by 5 and in 5/3 multiply both the numerator and denominator by 7

So a/b= 4×5/7×5

b/c = 5×7/3×7

a:b:c = 4×5:7×5:3×7

or, a:b:c = 20:35:21
