Answer:
13: 89.75
14: 39
15: 403
DISCLAIMER: This is all in EXACT answers
Step-by-step explanation: I hope this helps! (Not rounded; exact answers) I used long division.
TIP: Round up (or down) to find the rounded number. Remember, the number in the one's place between 0-4, you round down. You round up when the number in one place is 5-9. So,
718 rounded = 720
156 rounded = 160
3627 rounded = 3630
Now, divide the rounded answers by the number on the right, so the REAL answers are:
13: 90
14: 40
15: 403.3 (3 repeats forever)
I hope this helps ;)
