Question

Sydney measured a line to be 4.9 inches long. If the actual length of the line is 5.2 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

Answer 1

The percent error of the measurement will be 5.8%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Sydney measured a line to be 4.9 inches long.

And, The actual length of the line is 5.2 inches.

Now,

The percent error is calculated as;

The difference between the measures = 5.2 - 4.9

                                                            = 0.3 inches

So, The percent error = 0.3/5.2 x 100

                                  = 5.76%

Thus, The percent error of the measurement to the nearest tenth of a percent will be 5.8%.
