Clare estimates that her brother is 4 feet tall. When they get measured at the doctor's office, her brother's height is 4 feet, 2 inches.
the error, expressed in inches is 2 so what is the percentage of the actual height
To find the percentage of the actual height that the error represents, we need to divide the error by the actual height and then multiply by 100.
Error = 2 inches
Actual height = 4 feet, 2 inches = 4 feet + 2 inches = 50 inches
Percentage error = (Error / Actual height) x 100
Percentage error = (2 / 50) x 100
Percentage error = 0.04 x 100
Percentage error = 4%
Therefore, the error of 2 inches represents 4% of the actual height.
