Step-by-step explanation:

Let d represent the original denominator. Then the original numerator is ...

2d-15

The new numerator is ...

(2d-15) +5

and the new denominator is ...

d+7

The ratio of these is 2/3, so we have ...

$\dfrac{2d-15+5}{d+7}=\dfrac{2}{3}\\\\3(2d-10)=2(d+7) \quad\text{cross multiply}\\\\4d=44 \quad\text{add 30-2d}\\\\d=11\\\\2d-15=2(11)-15=7$

The original fraction is 7/11.
