Question

The denominator of a rational number is greater than the numerator by 10 If the numerator 8s increased by 1 the and denominator is decreased by 1 then expression for new denominator is ––––​

Answer 1

Let the numerator and denominator be x and y respectively

According to question, we get

$y = x \: + 10$

And

$\frac{x + 1}{y - 1} = \frac{x + 1}{x + 10 - 1} = \frac{x + 1}{x + 11}$

Hence, the expression is

$\frac{x + 1}{x + 11}$
