Question

Dayo read 4/5th of a story book which has 500 pages. How many pages of the book is not yet read by Dayo?

Answer 1

4/5 (four fifth) of 500 pages is $\frac{4}{5}$ times 500

$\frac{4}{5}$ times 500 is $\frac{4}{5}*500$, 

which is $4* \frac{500}{5}=4*100=400$

So Dayo read 400 pages of 500.

Dayo has not yet read 500-400=100 pages.


Answer: 100
