Question

Clare estimates that her brother is 4 feet tall. When they get measured at the doctor's office,

her brother's actual height is 4 feet, 2 inches.
2. What was the error, expressed in inches?

Answer 1

2 inches

Explanation:

Since his actual height was 4 feet and 2 inches, instead of the estimate of 4 feet, the difference was 2 inches.

This means the error in inches was also 2 inches, since the estimated height was 2 inches lower than the one at the doctor's office.

So, the error is 2 inches
