Answer:
- 18/24 and 8/24
- 5/15 and 9/15
- 6/9 and 4/9
Explanation:
We can go through the list of fraction pairs and see if the denominators are both factors of one of the offered "common denominator" values.
2, 9 -- no
4, 6 -- 24
5, 10 -- no
3, 5 -- 15
6, 9 -- no
20, 3 -- no
3, 9 -- 9
Based on the above results, the answers appear to be ...
common denominator 24: 18/24 and 8/24 (from 3/4 and 2/6)
common denominator 15: 5/15 and 9/15 (from 1/3 and 3/5)
common denominator 9: 6/9 and 4/9 (from 2/3 and 4/9)
