Question

Brendan is reading a book that is 360 pages long He 2 still has 3 of the book to read. If he plans to finish the book in the next four -nights, how many pages will he have to read each night?

Answer 1

We have a book of 360 pages.

He had already read 2/3 of the book, so there is 1-(2/3)=1/3 of the book left.

$1-\frac{2}{3}=\frac{3}{3}-\frac{2}{3}=\frac{1}{3}$

This means that 120 pages are left.

$360\cdot\frac{1}{3}=\frac{360}{3}=120$

If he wants to read the rest of the book in 4 nights, he has to read 30 pages a night.

$\frac{120}{4}=30$
