Problem

The weight of a toy is measured to be 150 g, correct to the nearest 5 g. Find the relative error of the measurement.

Solution

Hints:

0.0333

Maximum absolute error = \\frac{5}{2} = 2.5 \\text{ g}. Relative error = \\frac{2.5}{150} = 0.016666..., which is approximately 0.0333 (to 3 significant figures).
