make it one fraction the whole thing one fraction.
make the 2 a fraction with the same denomenator. it becomes 24/12
24/12 + 5/12 = 29/12
29/12 is the same as 2 5/12
to make it reciprocal you flip it so the denomenator becomes the numerator and vice versa
your answer is 12/29
hope this is right and helps
