In a weighing balance, Katie placed two 500 gram blocks on one side and 850 grams of sugar on the other side. How much more sugar does she need to add to balance the weights?
350 grams
150 grams
1350 grams
1850 grams
Your response: 150 grams
Correct response: 150 grams
Explanation: Two 500 grams = 2 x 500 = 1000 grams. To balance the weights, she needs to add 1000 - 850 = 150 grams of sugar.
