Question

Isabel and Jared each made a pan of brownies. Their pans of brownies were exactly the same size. After the first day, there was 1 4 of one pan and 2 12 of the other pan left. What fraction of the brownies were eaten? Show your work.

Answer 1

Answer:

19 / 20

Step-by-step explanation:

Amount of brownies left :

Pan 1 = 1/4

Pan 2 = 2 /12

Total fraction of brownies made = 1/1

Hence,

Fraction of brownies eaten from each pan :

Pan 1 :

1 - 1/4 = (4 - 1) = 3/4

Pan 2 :

1 - 2/12 = (12 - 2) = 10/12

Total fraction of brownies eaten :

Pan 1 + pan 2

3/4 + 2/10

(30 + 8) / 40

38 / 40

19 / 20

Hence, total fraction of brownies consumed = 19/20
