Answer:

I will convert these units already to the same unit like hrs to mins.

1. 20 mins to 180 mins so reduce using GCF 20,the ratio is 1 min to 9 mins
2. 36 out of 40 so reduce using GCF 4,the ratio is 9 out of 10
3. 4 months to 60 months so reduce using GCF 4, the ratio is 1 month to 15 months / 1 month to 1 ¼ year
4. 6 days to 14 days so reduce using GCF 2,the ratio is 3 days to 7 days / 3 days to 1 week
5. 3 liters of orange to 12 liters of water so reduce using GCF 3,the ratio is 1 liter of orange to 4 liters of water
