Answer:
15/2
Explanation:
If you need to simplify it/it can't be a decimal then 15/2 would be your answer.
Work:
30/4 = 7.5 (decimal)
15 times 2 = 30 (15 goes into 30 twice evenly)
15/2 is the simplest you can make it without it being uneven.
7.5
- 28
------------
20
- 20
--------------
0
(Not a square root! I just used it to show how its being divided. And also on the left of the '30' is a 4, so 30 divided by 4 and so on.)
Sorry if the answer looks messy!
