Mary prepared 40 pineapple fruit yogurt cups to sell at a school fair. She sold 5/8 of the cups. How many cups did Mary sell? (1 point)

To find the number of cups Mary sold, we multiply the total number of cups by the fraction she sold: 40 cups * 5/8 = (40/1) * (5/8) = 200 / 8 = <<40*5/8=25>>25 cups. Answer: \boxed{25}.
