Jill has 3 full pans of brownies.
• Each pan was the same size.
• She gave 3/8 of the original amount of brownies to her friends.
• She gave 1/4 of the original amount of brownies to her teacher.
Exactly how many pans of brownies does Jill have left for herself?

Answer 1

3/8

Explanation:

Based on the given information, Jill initially had 3 full pans of brownies. She gave away 3/8 of the original amount to her friends and 1/4 of the original amount to her teacher. To find out how many pans of brownies Jill has left for herself, we need to subtract the amount she gave away from the original amount.

First, calculate the total fraction of brownies she gave away: 3/8 + 1/4 = 6/16 + 4/16 = 10/16

Since the fractions have the same denominator, we can add them directly.

Now, subtract the fraction of brownies she gave away from the original amount: 1 - 10/16 = 16/16 - 10/16 = 6/16

Jill has 6/16 pans of brownies left for herself.

Simplifying the fraction, we get: 6/16 = 3/8

Therefore, Jill has 3/8 pans of brownies left for herself.
