We have been given two ratios and we are supposed to compare our ratios whether they are proportional or not.
1. We will reduce our fractions to compare our ratios. Let us simplify each of our given fractions.

Let us divide numerator and denominator with greatest common factor. We can see that 21 is GCF of our ratio.

Now we will simplify our second ratio.

GCF of our fraction is 32. Upon dividing our fraction by 32 we will get,
We can see that our both ratios are similar.
2. Now we will find decimal values of our fractions.


We can see that
.
Therefore, we can say that our ratios are proportional.
The number of degrees does it move in 2 1/5 hours is -66°.
<h3>How to calculate the number of degrees?</h3>
From the information given, it was illustrated that the hour hand of a clock moves −30° every hour.
Therefore, to calculate the degree for a number of hours, we simply have to multiply.
In this case, to get the degree for 2 1/5 hours will be:
= Degree every hour × Number of hours
= -30° × 2 1/5
= -30° × 2.2
= -66°
