Express each ratio as fraction in its lowest terms
18 hrs to 2 days
25cm to 3m
4 days To 2 weeks
48 secs to 5 mins
3kg to 800g
2 days = 48 hours
18/48 = 3/8
3m = 300cm
25/300 = ?
Use similar process for remaining problems.
18/48 = 9/24 = 3/8
25/300 = 25 /(3*4*25) = 1/12
48/(5*60) = (4*12)/(5*5*12) = 4/25
3/0.8 = 30/8 = 15/4
