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. -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...

Answer 1

1.) 2.4 = 24/10

2.) 74 = 74/1

3.) 17.3333333... = 17 + 0.333333,,, = 17 + 3/(10 - 1) = 17 + 3/9 = 17 + 1/3 = 17 1/3 = 52/3

4.) π is not a rational number
