Question

Hayden has read 3/5 of a book she has read 75 pages so far how many pages are in the whole book?

Answer 1

Let there are x number of pages in whole book. So 3/5 of a book is equal to 3/5x.

Determine the value of x.

$\begin{gathered} \frac{3}{5}x=75 \\ x=75\cdot\frac{5}{3} \\ =125 \end{gathered}$

So there are 125 pages in the whole book.
