Question

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. 5 6/11
6. -18
7. 0.6
8. 87.125
9. -30
10. -8.3
11. 58.25
12. 121
13. 4.5
14. 3 7/10
I am so confused!!!

Answer 1

1. 2.4 = 12/5 Rational
2. 74 = 74/1 rational
3. 17.333...=52/3 rational
4. pi can not be expressed as a fraction so irrational
5. 5 6/11 = 61/11 rational
6 -18 = -18/1 rational
7. 0.6=6/10 rational
...
Everything is rational other than number four
