My question is: Mary has 26 blue shirts and 36 brown shirts. If she gives away half of her blue shirts and a third of her brown shirts, how many shirts does she have left? Your thoughts:
Mary gives away 26 / 2 = 13 blue shirts. Mary gives away 36 / 3 = 12 brown shirts. Mary has 26 - 13 = 13 blue shirts left. Mary has 36 - 12 = 24 brown shirts left. Mary has 13 + 24 = 37 shirts left. The final answer: 37.
