Question 203727
Basically these questions are about making a formula. 
I like #3. 
Nine divided by a number is equal to three....
Make these words into numbers
9/x=3
How do you solve for x?? We must get it off the bottom by mult. both sides by x

x(9/x)=3(x)
which is 9=3x
Then divid by 3 to get x by it self.. 
9/3=x
3=x
 try the others..if you still have problems repost the questions with where you are finding the troubles.
