Mary prepared 40 pineapple fruit cups to sell at a school fair . she sold 5/8 of the cups. how many cups did mary sell?

To find out how many cups Mary sold, we need to calculate 5/8 of 40 cups.

5/8 * 40 = (5 * 40)/8 = 200/8 = <<200/8=25>>25

Mary sold 25 pineapple fruit cups.

To find out how many cups Mary sold, we need to calculate 5/8 of the total number of cups.

Step 1: Multiply 40 by 5
40 * 5 = 200

Step 2: Divide the result by 8
200 / 8 = 25

Mary sold 25 pineapple fruit cups at the school fair.

To find out how many cups Mary sold, we need to multiply the total number of cups she prepared by the fraction of cups she sold. Here's how we do it:

Step 1: Calculate the number of cups Mary sold
First, we need to find 5/8 of the total number of cups Mary prepared. To do this, we multiply:

40 (total number of cups prepared) * 5/8 (fraction of cups sold)

Step 2: Simplify the fraction
To simplify 5/8, we find the Greatest Common Divisor (GCD) of the numerator (5) and denominator (8). In this case, the GCD is 1, so the fraction cannot be simplified any further.

Step 3: Perform the multiplication
Now we multiply the numerator (5) by the total number of cups (40) and divide it by the denominator (8):

(5 * 40) / 8 = 200 / 8

Step 4: Simplify the resulting fraction
To simplify 200/8, we divide both the numerator and denominator by their Greatest Common Divisor, which is 8. Dividing both by 8 gives us:

200 / 8 = 25

Therefore, Mary sold 25 pineapple fruit cups at the school fair.
