Question

Susan ate 1/6 of a pumpkin pie. Joseph ate 3/4 of the same pumpkin pie. How much pie is left

Answer 1

Answer:

1/12 of the pumpkin pie is left.

Explanation:

To solve this you have to add 1/6 and 3/4, but in order for you to do that, you have to change each of the fraction so they have the same denominator. To do this you have to find out what number 6 and 4 can both go into, which is 12. So since you know that 6 times 2 is 12, you would multiply two to both the numerator and denominator, and get 2/12 as the result. Next, you have to the same thing to 3/4, except since 4 times 3 is 12, you would multiply 3 to both the numerator and denominator instead, so you should get 9/12. The final thing that you have to do in order to get your answer is add 2/12 and 9/12 which would be 11/12. Since you know that 11/12 is how much Susan and Joseph ate, the remaining 1/12 is how much of the pie is left.

I hope this helped you :D

Answer 2

First you need the same denometer Which is 12
9/12+2/12 = 11/12
So 1/12 pie is left
