Prove it is rational by writing it as a quotient of two integers. answer these problems, i need to check my answers. ignore the blank ones, i was able to check them. you! 1. 2.4 2. 74 3. 17.3333333… 4. π 5. 6. –18 7. 8. 87.125 9. –30 10. –8.3 11. 58.25 12. 121 13. 4.5 14.

1.2.4 = 24/10

2.74 = 74/1

3.17.3333333… = 52/3

4.π - not rational

6.–18 = -18/1

8.87.125 = 87125/1000

9.–30 = -30/1

10.–8.3 = -83/10

11.58.25 = 5825/100

12.121 = 121/1

13.4.5 = 45/10

Most of the decimals can be reduced to lower terms by removing at least one factor of 2 or 5. If all you want is a ratio of integers, that is irrelevant.

What are the options
