0.75
Explanation:
First, you would need to convert it to a fraction for it says "of the", which is one of the key words to a fraction.
In fraction form it would look like this:
9/12
Now, if you remember, fractions are actually division; meaning this problem is also 9 divided by 12. So let's do that!
9 divided by 12 = 0.75.
You can also simplify the fraction; 9/12 is the same as 3/4, and you should know that 3/4 is the same as 0.75
