Question

If the first chapter of a certain book is 32 pages long and makes up 4% of the book, how many pages does the entire book have?

Answer 1

First chapter

32 pages

4% of the book

How many pages?

P = total pages

32 pages = P*4%

$\begin{gathered} P=\frac{32\text{ pages}}{4\text{ \%}} \\ P=\frac{32\text{ pages}}{0.04} \\ P=800\text{ pages } \end{gathered}$

The book would be 800 pages
