Question

A dump truck brought 1/3 of a ton of rock on the first trip, 5/6 of a ton on the second trip, and 5/12 of a ton on a third trip. What was the total weight of the rock?

Answer 1

First convert the numbers to get the same denominator.

1/3=4/12

5/6=10/12

5/12

Then, add them all together.

4/12+10/12+5/12 = 19/12

Then reduce.

1 7/12

Your answer is 1 ton and 7/12 of a ton.
