plsszzz do no.(iv) fast ​

Answer 1

$given - \\ \frac{a}{b} = \frac{3}{2} \\ \frac{b}{c} = \frac{3}{2} \\ mutiplying\: both \: the \: eq \\ = \frac{a}{c} = \frac{9}{4} \\ we \: have \: to \: find \: the \: value \\ \: of \: \frac{a + b}{b + c} = \frac{a}{b} + \frac{b}{b} + \\ \frac{a}{c} + \frac{b}{c} \\ = \frac{3}{2} + 1+ \frac{9}{4} + \frac{3}{2} \\ = 4 + \frac{9}{4} \\ = \frac{25}{4}$

Hope this helps you.
