Question

Della has 493 stamps in her stamp collection. She can put 16 stamps on each page of her album. How many pages can she fell completely?

Answer 1

She can fill 30 pages because 16*30 is 480, so you try 1 up, 16*31 is 496, which is too high, so you go with the highest number you can get without going past 493, and get 30!

Answer 2

Just divide the number of stamps by the number of stamps per page

$\frac{493}{16}$=30.8125

She can fill 30 pages completely and have 13 stamps left over.
