Question

Three students are from a plate of cookies.Daniel ate 1/12 of the cookies, Mariel ate 4/12 of the cookies, and Tamika ate 2/12 of the cookies.What fraction of the cookies was left on the plate?

Answer 1

Answer:

5/12  of cookies left on the plate

Step-by-step explanation:

we have to add to know what part of the dish ate and then subtract it from the total

1/12 + 4/12 + 2/12 =

when we are adding fractions with the same denominator we simply add the above

1 + 4 + 2 = 7

1/12 + 4/12 + 2/12 = 7/12

now to the total of the plate that would be 1 we subtract what they ate

1 - 7/12 =

the whole 1 can be expressed as 12/12 since if we do the 12/12 = 1 account

12/12 - 7/12

for the subtraction with the same denominator the same thing happens as for the sum, we only do it with the top

12 - 7 = 5

12/12 - 7/12 = 5/12

Answer 2

Answer: the fraction of cookies left on the plate was 5/12.

Step-by-step explanation:

The initial amount of cookies on the plate is taken as 1.

Daniel ate 1/12 of the cookies, Mariel ate 4/12 of the cookies, and Tamika ate 2/12 of the cookies. This means that the total number of cookies that they ate is

1/12 + 4/12 + 2/12 = 7/12

Therefore, the fraction of the cookies was left on the plate would be

1 - 7/12 = (12 - 7)/12 = 5/12
