Question

the denominator of a rational number is 7 more than the numerator .if 1 is added to the numerator and 1 is subtracted from the numerator the new number is 1 / 2 . find the rational number​

Answer 1

Step-by-step explanation:

Let numerator be x and denominator be x+7.

According to the question:$\frac{x + 1}{x + 7 - 1} = \frac{1}{2}$

$\frac{x + 1}{x + 6} = \frac{1}{2}$

$2(x + 1) = x + 6$

$2x + 2 = x + 6$

$x = 4$
