pre-cal is short for pre-calibration

precal · Answer

create a proportion
sugar/cookies
1.25/20=x/14
cross multiply and solve for x
14(1.25)=20x     divide by 20
.875 or 7/8 = x

anonymous · Answer

No the answer was 7/8 It was right

precal · Answer

I believe this is a simple proportion problem.  Let's look at if the solution is reasonable.  You need 1.25 cups of sugar to make 20 cookies.
If 1.92500 is correct, why would you need more sugar to make less cookies.
Note:  we are trying to make 14 cookies.
