So we want to subtract the second number by the first because, 1st is the no. of books last week, 2nd is this weeks, we want to work out the difference of the two numbers, this can also be known as subtract $3\left(\begin{matrix}1 \\ 5\end{matrix}\right)$ - $1 \left(\begin{matrix}4 \\ 5\end{matrix}\right)$

put the whole numbers in the fraction as well last week books= 16/5 this weeks =9/5 now you just need to minus the numerators 16-5=7, therefore the answer is 7/5 you can turn that into the whole number again you will get 1 2/5
