Question

2. If A:B = 4:9 and A: C = 2: 3, find B: C and A:B:C.​

Answer 1

Hey friend,

Here is the solution :-

$a : b \: = \frac{a}{b} = \frac{4}{9} \\ \\ a : c \: = \frac{a}{c} = \frac{2}{3} \\ \\ now \: \frac{a}{c} \times \frac{2}{2} = \frac{2}{3} \times \frac{2}{2} = \frac{4}{6} \\ \\ here \: we \: get \: \frac{a}{c} = \frac{4}{6} \\ \\ a = 4 \: \: \: \: b = 9 \: \: \: \: c = 6$

So, B : C = 9 : 6 and A : B : C = 4 : 9 : 6
