Total number of Matt's and Sarah's pen = x+y

Total number of pens =

Take LCD 12

Now add the numerators

To express the number of Matts pens as a fraction

We divide the number of Matt's pen 'x'  by the total number of pens

we cancel out x at the top and bottom

Take reciprocal of 17/12 and multiply with top 1

So answer is 12/ 17
