Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
If nine out of ten students (
) prefer math class over lunch, then we can infer that one out of ten students (
) do not.
or 10%
As we can see, this equals a 10% of the students that were asked. If <u>200 students</u> were asked, we would need to find what 10% of 200 would be. We can do this by multiplying 200 by the decimal form of 10% like so,

So we can see that <u>20 students</u> do NOT prefer math over lunch.
