A construction company used up 7 and a half tons of cement on one project and 9 and three-quarters tons on another project. How many tons of cement did they use in total?

Answer 1

To find the total tons of cement used, we need to add the amount used on each project.

First, let's add the 7 and a half tons used on the first project and the 9 and three-quarters tons used on the second project:

7.5 + 9.75 = 17.25

Therefore, the construction company used a total of 17 and a quarter tons of cement.
