Our current ratio is:
9 : 33
To simplify this, we need to see what the greatest common factor between these two numbers are. The greatest common factor is a number in common that multiplies into both numbers.
As an example, I will use our current ratio.
Let's see the factors of 9.
9 = 1 x 9, 3 x 3.
Now let's see the factors of 33.
33 = 1 x 33, 3 x 11.
Now the greatest common factor is what will help us simplify our ratio.
3 is the greatest common factor between 9 and 33.
Now divide both numbers by 3.
3:11 is your new and simplified ratio.
I hope this helps!
