Jeremy is playing a game called “Rational Round Up” where he has to collect all the numbers in a maze that are rational and then get to the end of the maze. When he collects a number he must prove it is rational by writing it as a quotient of two integers. Help him determine how to prove that each of the following numbers is rational.

1. 2.4
   
2. 74
   
3. 17.3333333...
   
4. π
   
5. -18
   
6. 87.125
   
7. -30
   
8. -8.3
   
9. 58.25
   
10. 121
    
11. 4.5
    
    

It is very confusing... I just need answers and you don't need to explain if you don't want to...
