No correlation I believe.
I believe the answer is $17500
Eleven Twentieths of the pie are left, so that's 11/20
Method to solve;
Since its given a 1/4 and a 1/5 it's easiest to convert these to twentieths (the lowest common multiple of 4 and 5)
So 1/4= 5/20
1/5 = 4/20
How much is eaten = 5/20 + 4/20 = 9/20
How much remains = Total (20/20) - How much eaten (9/20) = 11/20
1/2, try taking out the biggest number out of both of the numbers, in this case five can be taken out of both the numbers, leaving you with 1/2 :)
Start by changing the white and brown sugar to where u can add it.
(1*3)/(4*3) =3/12
(2*4)/(3*4)=8/12
Add those
11/12 so she can top 11
