Answer:
20
Step-by-step explanation:
"Nine out of ten students prefer math class over lunch. How many students would not prefer math class if 200 students were asked about their preferences, if they followed the same percentage?"
Nine out of ten
Change total (ten) to 200
Ratio: 9/10 = x/200
180/200 = x/200
x = 180 prefer math
200 - 180 = 20 do not prefer math
