Question

Tom has 2 boards that are the same length as Bill's. He says that he found the total length of the boards by adding 28 twelfths and 23 twelfths. Does his method work? Explain.

Answer 1

Answer:This method does not work

Explanation:

Since the 2 boards have the same length, the addition of the 2 boards should be the same.

Since 28 does not equal to 23, the method will not work.
