Question

The numrator of a rational no is smaller than its denominator by 4. If the numerator is increased by 3 and is decreased by 5,the no becomes 2. Find the rational number ​

Answer 1

Let the numerator be x

So the denominator is x+4

If numerator is increased by 3 and denominator is decreased by 5, then the fraction becomes 2.

$\frac{x+3}{x-1} = 2$

$x+3=2x-2$

$x = 5$

So the rational number is $\frac{5}{9}$
