Answer:

1. 1/12

2. 5/12

3. 6/12 or 1/2

4. 6/12 or 1/2

5. 4/12 or 1/3

Step-by-step explanation:

1. 3 is a red ball, only 1 out of 12 red balls. so 1 out of 12 or 1/12

2. 1,2,3,4 and 5 are the red balls less than 6, they're 5 out of 12. or 5/12

3. 2,4,6,8,10 and 12 balls. Six balls out of 12 balls.

so 6/12 or 1/2 (lowest term)

4. 1,3,5,7,9,11,13 , same six balls out of 12 balls

5. 9,10,11,12 are the red balls greater than 8. with a total pf 4 out of 12. 4/12 or 1/3 (lowest term)
