Answer:

a) 3 :1

b)8 : 3

Step-by-step explanation:

When finding ratio's, both should be in same units.

1.8 kg = 1.8 * 1000

         = 1800.0 grams

1.8 : 600 = 1800 : 600 = 18 : 6

              = 3 : 1

b) 1 hour  20 minutes = 60 + 20 = 80 minutes

1 hour  20 minutes : 30 minutes = 80 : 30

                                                     = 8 :  3
