Answer 1

hope it will help you:-)

Answer 2

Explanation:

given

$\frac{a}{b} = \frac{7}{3}$

then

3a=7b

then

$a = \frac{7b}{3}$

now take

$\frac{a + 2b}{a - 2b}$

put

$a = \frac{7b}{3}$

then we will get

$\frac{13b}{3} \times \frac{3}{b}$

Hence we will get

$\frac{13b}{b}$

so

ANSWER IS 13

THE ANSWER REQUIRED

$\frac{a + 2b}{a - 2b} = 13$
