How did you get that?

If there was 5 left...and it was 1/2 left ..split into 3 pieces..multiply that 5x3..to complete 3/3 for that half..
Then double the number..so u get 15x2 which is 30..
Pretty much split both halves into sets of 3..to get 6 of 1/3rds..and have 5 multiplied by those 6 which is still 30..

Here's how you do this problem:
5(3/2)
(5/1)(3/2)
=15/2
15/2(2)
=15
How is everyone getting 30? Did I miss something? I'm going into AP Calc next year so I question how I am making some huge mistake on this.

Okay sorry it should be:
x/2-(2/3)(x/2)=5
x(1/2-2/6)=5
x(3/6-2/6)=5
1/6x=5
x=5(6)
x=30
NOT:
1/2(2/3x)=5
2/6x=5
1/3x=5
x=5(3)
x=15

no I missed part of the question sorry

The part you missed was not problematic. It didn't include the numbers and was easy to figure out. Unless someone else took some cookies 30 cookies is still the answer.

30 cookies. She took 2/3 with 5 left over, which means 5 is 1/3.
5 (1/3) x 3 = 15 (3/3)
Her brother took 1/2 and there was 15 cookies left
15 (1/2) x 2 = 30 (2/2)
She baked 30 cookies

There was 1/6 of cookies left on the plate from the start. So, if there were 5 cookies then, all we have to do is multiply 5 by 6 (because 1/6x6=1). Your answer is 30.
