Question

Plant B is 6 2/3 inches tall. and C is 4 4/15 inches tall. Complete the sentences and show your reasoning

Plant C is (answer) times as tall as plant B
Plant C is (answer) inches (answer) taller or shorter than plant B

Answer 1

Explanation:

Plant B is taller than Plant C. We need to determine by how much. To do this, we divide 6 2/3 inches by 4 4/15 inches. The LCD is 15, and so we have:

6 10/15 100/15

----------- or ------------- = 100/64 = 20/16 = 5/4

4 4/15 64/15

Plant B is 1 and 1/4 times taller than Plant C. This can be restated as Plant C is four fifths as tall as Plant B.

Plant C is shorter than Plant B, as we saw earlier. The difference is found through subtraction: 100/15 - 64/15 = 36/15 inches = 12/5 inches shorter, or 2 2/5 inches shorter
