Use Componendo and dividendo theorem.

If A/B = C/D = > (A+B)/(A-B) = (C+D)/(C-D) by Componendo and dividendo.

You will achieve at the right answer in seconds.

There's a rule, If you keep adding 1 to both numerator and denominator of a fraction, the value of the fraction approaches 1. Applicable in both cases 1) when numerator > denominator (value will increase) and 2) numerator < denominator (value will decrease).
