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. What is the percent error between the old and new balance?
