Since the digits after decimal point is repeating in a pair of 36 when we multiply $$\frac{m}{n}$$ by 100 we get 36.363636.....

Therefore, $$100 * \frac{m}{n}- \frac{m}{n} = 36$$
or, $$99 \frac{m}{n} = 36$$
or, $$99m = 36n$$
The ans requires the value of m such that m/n is reduced to its lowest fraction
Therefore when dividing both sides by 9 we get,
$$11m = 4n$$
or, $$\frac{m}{n}$$ = $$\frac{4}{11}$$
Hence, m = 4
