Answer:

Step-by-step explanation:

To convert the following to ratio goes thus:

1.20 to 3.80

We can first change to fraction and divide. This will be:

= 1.20 / 3.80

= 0.6 / 1.90

Therefore this gives a ratio of 3:19

4.8mm 1.44cm

First we need to convert 1.44cm to mm and since 10mm = 1cm. This will be:

1.44cm = 1.44 × 10 = 14.4mm

4.8mm to 14.4m

= 48mm / 144m

= 1/3

This gives a ratio of 1:3
