Question: Colby harvested his mango trees, the total mangoes he harvested is 60 kilograms. He sold 20 kilograms to the market and sold the remaining half to his community. If each kilogram contains 8 mangoes, how many mangoes does he still have? Think carefully first, then make a decision:
He has 60 - 20 = 40 kilograms of mangoes left after selling them to the market. Colby sold 1 / 2 x 40 = 20 kilograms of mangoes to the community. Therefore, Colby still has 20x8 = 160 pieces of mangoes. So the answer is 160.
