Question

Three girls are selling cases of corn to earn money for a band trip. So far, Emily sold 2 3/4 cases, Brenda sold 4 1/4 cases and Shannon sold 3 1/2 cases. How many cases of popcorn have the girls sold in all? The girls will need to sell a total of 15 cases in order to have enough for trip. They all want to sell an equal amount of the remaining cases or its parts.

Answer 1

So first you need to find a common denominator. A number that all of the denominators go into is 4. Then you add up the numerators and whole numbers. So the answer to this problem would be... 10 1/4 because... 4,4 and 2 all go into 4 so 4 is the common denominator. 1/4 + 3/4 + 1/4= 5/4 = 1 1/4. Plus the whole numbers adds up to 10 1/4

Answer 2

They will not be able to go on the trip. They only sold 10 2/4. Hope this helps!
