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 = 12/5
2. 74 = 74/1 rational
3. 17.3333333… = 52/3 rational
4. π pi cant be expressed as a fraction so irrational.
5. 61/11 rational
6. –18 = -18/1 rational
7. = 6/10 rational
8. 87.125
9. –30 = -30/1 rational
10. –8.3
11. 58.25 = 58 ¼ rational
12. 121
13. 4.5
14. = 71/10 rational
I have completed a few i just need help on the rest.

ummmm? hello?
Looks like you handled it pretty well.
.125 = 125/1000 = 1/8
So, 87.125 = 87 1/8 rational
All terminating decimals work this way
you got -30, but can't figure 121???
