If the teacher wants to split an eraser into 5 pieces she/he could but they would be small pieces. if she/he splits them, each student would get one small piece and since there are two erasers, then each student would get 2 small pieces of an eraser.
First, you do a proportion. X/48=25/100.
25 times 48 equals 1,200. Now divide 1,200 by 100 which equals 12. This means 12 cookies is 25% of 48 cookies. Now do 48-12 which is 36. YOUR ANSWER IS 36
