= 3 : 5

2.. 2 year's 6 month's and 1 year 6 month's

= 2 year's= 2 × 12 months

= 24 months

24 + 6 month's = 30 month's

1 years

1 years 6 months

= 1 year = 12 months

12 + 6 months = 20 month's

= 30 / 20 month's

= 3 /2 month

= 3 : 2

3.. 2 hours and 1 hours 20 minutes

= 2 hour's = 2 hours × 60 minutes

= 120 minutes
