In order to subtract the fractions, they need to have the same denominator.

So, to put the fractions in the same denominator, let's find the least common multiple between them:


\begin{gathered} 16\to2\cdot2\cdot2\cdot2 \\ 8\to2\cdot2\cdot2 \\ \\ \text{LCM}\to2\cdot2\cdot2\cdot2=16 \end{gathered}

So, calculating the subtraction, we have:


(13)/(16)-(3)/(8)=(13)/(16)-(6)/(16)=(7)/(16)

So the resulting fraction is 7/16.
