Answer:
8
Step-by-step explanation:
Let's set this up to see if we can simplify it a bit:

Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top. And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom. Now that looks like this:

10 divided by 5 is 2, and 2 cubed is 8
If you turn 9 1/3 in to a decimal and 3 1/2 in a decimal also
9 1/3 = 9.3 and 3 1/2 =3.5
9.3+3.5 =12.8
12.8=12 4/5
7,440 I believe, all you need to use is basic subtraction for this.
The GCF of 45 and 75 is 15.
So, divide both numbers by 15.
45/15 = 3
7515 = 5
Therefore, the simplified version of the ratio is 3 to 5
Best of Luck!
