Your answers for the free throws and books are wrong.
A for the free throws question and C for the books question?
Now they're all correct.
First one is right, the last two are wrong.
How are you doing these?
Why not use a simple ratio
1/25 = 3/x
x = 75 , you had that one correct
20/25 = x/75
25x = 1500
x = 60 ----- which is A
100/3 = x/12
3x= 1200
x = 400 ---- which is C
