Question

Nine out of ten student prefer math class over lunch. How many students do not prefer math if 200 students were asked

Answer 1

If nine out of ten students prefer math class over lunch then that's 90%. Which means 10% of the 200 don't prefer it. 200/10= 20 people do not prefer math

Answer 2

Answer:

20 students do NOT prefer math over lunch.

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 ($\frac{9}{10}$) prefer math class over lunch, then we can infer that one out of ten students ($\frac{1}{10}$) do not.

$\frac{1}{10} = 0.10$ or 10%

As we can see, this equals a 10% of the students that were asked. If 200 students 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,

$200 * 0.10 = 20 students$

So we can see that 20 students do NOT prefer math over lunch.
