Answer:

12/5, 7/10, and 8/5

Step-by-step explanation:

12/5, 7/10, and 8/5 all have ratios that cannot be simplified because that is their next lowest common factor is 1.

However, 9/15 can be simplified because they have the common factor 3.

If you take the numerator and denominator and divide them both by 3, you get the fraction 3/5.
