Question 2 • FL-2000310-Biology 1 Sem 1 - Flex

Mr. Nakamora wants to test the accuracy of an old balance in his classroom compared to a brand-new balance that he knows is accurate. He weighs an object on the old balance and finds it to have a mass of 15.6 grams. The same object weighs 15.9 grams on the brand-new balance.

Answer
A
0.97%
B
1.29%
C
1.89%
D
2.29%

Explanation

Use the brand-new balance’s accurate mass, 15.9 grams, as the reference. The old balance differs by |15.6 − 15.9| = 0.3 grams, so the percent error is (0.3 ÷ 15.9) × 100 ≈ 1.89%. The correct choice is 1.89%.
