Question

Tanisha weighed a wooden block that was labeled 253.8 grams, and found that it actually weighed 235 grams. What was the percent error in the labeling of the block? ( Round to the nearest 10th of a percent. )

Answer 1

8%

Explanation:

If the block weighs 235 grams, we can do (253.8-235)/235=18.8/235=0.08. Because it's percent, we need to multiply by 100, so the answer is 8%.
