Question

9 out of 10 students prefer maths class over lunch how many students do not prefer math if 200 students were asked?​

Answer 1

20 students

If 9 out of 10 student prefer math over lunch, then 1 out of ten DO NOT. With this information you can set up a simple proportion:
`(1)/(10) =(x)/(200)`.

To solve for x, you cross multiply as follows:

1*200=10x

200=10x

20=x

Hence, x equals 20, and 20 students do not prefer math over lunch.

Hope I helped!!!!!!!!!!!!!:)

Answer: 180
