Do you divide if the question is "Martha had 154 stamps and her sister had 248 stamps. They combined their collections & put the stamps in a album. If they want to put 8 stamps on each page, about how many pages would they need?

Yes

Step-by-step explanation:

In this question, you would first need to add together Martha's stamp collection with her Sister's stamp collection to get the total. Once you have this total then you would divide by 8 in order to calculate the total number of pages (x) that you would need to completely use all of the stamps. This is calculated like so...

(154 + 248) / 8 = x

402 / 8 = x

50.25 = x

Based on these calculations you would need 50.25 pages but since you cannot have 0.25 of a page we need to round this up to the nearest whole page which would make the total number of pages needed 51 pages
