Answer: 18 students do NOT prefer pop music.
Explanation: 2/5 of 30 students do PREFER pop music, that means the rest, which is 3/5, does NOT prefer pop music
3/5 of 30 is 18
30 divided by 5 x 3 = 18
You can trust this answer
Goodluck!
First, you calculate the total amount of parts : 2 + 5 = 7
Next, divide the number by the total amount of parts : 28 ÷ 7 = 4
After that, you multiply the answer by the amount of parts needed on both sides of the ratio : 4 × 2 = 8 and 4 × 5 = 20
Finally put these answers back into the ratio : 8:20
So there are 8 students in the play
To check, make sure both sides of the ratio add up to the original number : 8 + 20 = 28
