Firstly it is important to make both the units same for creating a ratio. Here one of the number mentioned is in centimeter while the other number that is mentioned is in millimeter.
We already know
1 cm = 10 mm
Then
120 cm = 10 * 120 mm
= 1200 mm
Now we can go for creating the required ratio.
So the ratio that compares 1200 mm to 80 mm is = 1200:80
= 120:8
= 15:1
So the correct ratio is 15 to 1. The correct option among all the options given in the question is option "C".
