Question

if a ratio b is equal 7 ratio 5 and b ratio C is equal 9 ratio 14 find a ratio c​

Answer 1

Given,

                $\frac{a}{b} = \frac{7}{5}$     --(1)

  and,        $\frac{b}{c} = \frac{9}{14}$   --(2)

                 Multiply (1) and$\frac{a}{c} = \frac{a}{b} . \frac{b}{c}$

               $\frac{a}{c} = \frac{7}{5} . \frac{9}{14}$ = $\frac{9}{10}$
