Question

if a ratio b is equals to 3 ratio 5 and b ratio C is equals to 4 ratio 7 find a ratio B ratio c ???​

Answer 1

Answer:

(a/b)=3/5

(b/c)=4/7

b=(4/7)*c---let this be eqn 1

a=(3/5)*b--------eqn2

then put eqn 1 we get

a=(3/5)*(4/7)*c=(12/35)*a

therefore a:b:c=(12/35):(4/7):(1)

= 12:20:35
