Question

Katherine had 7/2 full pans of brownies. each pan made 10 brownies. she gave 2/5 brownies to her friends. how many brownies were left with Katherine?​

Answer 1

Step-by-step explanation:

We start with 7/10

We take from that 2/5 OF 7/10

 

You are looking to find:

7/10 - (2/5)(7/10)

= 7/10 - 14/50

Find lowest common denominator which will be 50

= (7/10)(5/5) - 14/50

= 35/50 - 14/50

= (35 - 14)/50

= 21/50 left

Answer 2

Answer: 21/50

Step-by-step explanation:

3/5 OF 7/10 = (3/5) X (7/10) = 21/50.

The answer is 21/50 of the brownies is left
