Question

Solve the following
Roger has 105 photographs. He can fit 4 on a page in a photo album. If an album has 18 pages, how many albums should he buy?​

Answer 1

Answer:

Step-by-steFirst, we need to work out how many photographs Roger can fit in one album. We do this by multiplying the number of photos per page by the  number of pages, so:

4 x 18 = 72

Then, we need to work out how many spare photographs Roger has left. We can do this by doing the math:

105 - 72 = 33

Or, we can just double 72 and see if the result is equal to, or greater than, 105. This is probably easier, as it's quite clear that 72 x 2 is going to be bigger than 105 (it's 144, in fact).

This means, to accommodate all his photographs, Roger will need 2 photo albums.

He won't fill the second one completely, though!p explanation:
