Answer:
28.75 or 28 3/4
Step-by-step explanation:
This equation is made for Long Division:
115/4
4 cannot go into 1 evenly.
4 can go into 11, 2 times.
4x2=8
11-8=3
4 can go into 35, 8 times.
35-32=3
Add a zero at the end, then divide 4 into 30.
4 goes into 30, 7 times.
30-28=2
Add another zero, then divide again.
4 goes into 20, 5 times.
20-20=0
So, after you hit an even number you can stop dividing and put in your answer.
28.75
