Question

If a : b= 1:2, b: c = 3:2,d: c= 5: 6, then find a :b:c:d​

Answer 1

$\huge\tt\purple{Answer:}$

$\frac{a}{b} = \frac{1}{2}$

$\frac{b}{c} = \frac{3}{2}$

$\frac{d}{c} = \frac{5}{6}$

If, d/c = 5/6 . Then, c/d = 6/5

$\frac{a}{b} = \frac{1}{2} \times \frac{3}{3} = \frac{3}{6} \times \frac{6}{6} = \frac{18}{36}$

$\frac{b}{c} = \frac{3}{2} \times \frac{2}{2} = \frac{6}{4} \times \frac{6}{6} = \frac{36}{24}$

$\frac{c}{d} = \frac{6}{5} \times \frac{4}{4} = \frac{24}{20}$

We made b and b common and c and c common.

Hence,

a:b:c:d = 18:36:24:20
