Answer 2

Answer:

m = 5 and n = 1

Explanation:

$\frac{3}{m + n} = \frac{4}{2(m - n)}$

$\frac{3}{m + n} = \frac{4}{2m - 2n}$

Cross Multiplication :-

3(2m-2n) = 4(m+n)

6m-6n = 4m+4n

6m-4m = 4n+6n

2m = 10n

$\frac{m}{n} = \frac{10}{2} = \frac{5}{1}$

m=5 and n =1 i.e. a natural number and less than 6
