Answer:
15 are covered with sprinkles (3/24)
Explanation:
First you need to find the common denominator for the fractions, that'll be 24. Then you convert them to get these new fractions.
8/24 covered in peanuts
9/24 covered with chocolate chips
4/24 covered with coconut
Now add those numbers to get 21/24 That's how many have been covered to find how many have sprinkles you subtract. To get 3/24
To find the exact number divide 120/24 to get 5 times 3 to get 15.
