Samuel, Tasha, and Ben are each growing plants. They want to know whose 1pcrounds to 7.45 inches when rounded to the nearest hundredth. Samuel's is7.443 inches. Tasha's is 7.455 inches. Ben's is 7.446. Whose plant rounds to7.45 inches?

Answer 1

When we round a number if the last digit is equal or greater than 5 we round up and if it is lower than 5 we round down. In this case we have:

Samuel: His plant is measuring 7.443 inches, the last digit is 3, therefore we must round down, which would be 7.44

Tash: Tasha's plant is measuring 7.455 inches, the last digit is 5, therefore we must round up. Which would be 7.46

Ben: His plant is measuring 7.446 inches. The last digit is 6, therefore we must round up. Which would be 7.45.

The answer is Ben.
