Antonio is a boy who eats a lot and his weight is 50 kilograms. Antonio's sister, who is an athlete, weighs 12 kilograms less than him. How much do the two siblings weigh together? Give me reasons, before answering the question
Antonio's weight is 50 kilograms. His sister weighs 12 kilograms less than him so she weighs 50 kilograms - 12 kilograms = 38 kilograms. The weight of the two siblings combined is 50 kilograms + 38 kilograms = 88 kilograms. So the final answer is 88.
