The answer is 2, and it's quite a simple equation, really!

How To Work Out The Answer

First, 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!

I'm really a fan of photography. That's why I go to the park every day and take pictures of nature. However, recently I noticed that there was very little memory left and decided to free up space. Here I learned how to transfer photos from your Mac or Windows PC to your iPhone. So if you like to take pictures, do not forget to transfer photos to your computer.
