Question

If a number y is subtracted from both the numerator and denominator of 13/23, the resulting fraction is ⅓. What is the value of the number y?

Answer 1

Answer:

8

Step-by-step explanation:

Subtract y from numerator and denominator of 13/23,

                                 $=\frac{13-y}{23-y} =\frac{1}{3}$

                            $39 - 3y = 23-y$

                                    $2y=16$

                                     $y=8$
