A student measured the length of a table to be 100 CM’s but the actual length is 125 CM what is the percent error in the measurement rounded to the nearest whole percent

To calculate the percent error, you need to find the absolute value of the difference between the measured value and the actual value, divide it by the actual value, and then multiply by 100 to get the percentage. Finally, round the result to the nearest whole percent.

First, calculate the absolute difference between the measured and actual values:
Absolute difference = |100 - 125| = 25

Next, calculate the percent error:
Percent error = (Absolute difference / Actual value) * 100 = (25 / 125) * 100 = 20

Rounding to the nearest whole percent, the percent error is 20%.
