Answer 1

So, 150 people are in sixth grade at a middle school.
Out of 150 people, 12 of them are left-handed and 138 are right-handed.
What do you do??
You have to find out how to set up your equation.
Cross multiply.
Divide what you get after the multiplying.
You get your answer and check if it was correct.
So how do you think that you have to set up this equation??

Answer 2

Maybe you have to put the x over 100, then 12 over 150

Answer 3

The answer is B

Answer 4

12*100=1200
150*x=150x
1200/150x=8
This means that your answer is probably B.
Hopefully, this helped you :)
