A factory makes sheets of metal that are 2 3/4 inches thick. If a worker at the factory makes a stack of 2 of the sheets, how many inches thick will the stack be?

Question

Simplify your answer and write it as a fraction or as a whole or mixed number.

inches

Answer 1

The stack will be 5 1/2 inches thick.

To see why, you can add 2 3/4 twice:

2 3/4 + 2 3/4 = 5 6/4

Simplifying by dividing the numerator and denominator by 2:

5 6/4 = 5 3/2 = 5 1/2

So the stack will be 5 and 1/2 inches thick.
