Question

Dan has a board that is

8 3/4
feet long. He cuts off
4 5/6
feet and says he has
4 1/12
feet left. Which of the following explains whether Dan is correct?

Answer 1

• He is wrong.
• The answer is 3 11/12.

Explanation:

Given equation:

• 8 3/4 - 4 5/6

Simplify:

• 8 9/12 - 4 10/12

Solve:

• 8 - 4 = 4
• = 9/12 - 10/12
• = 21/12 - 10/12
• = 11/12
• = 3 + 11/12
• = 3 11/12.

He is wrong.

He was off by 3 digits.
