Answer:

9 : 10

Step-by-step explanation:

First the ratio will be 63 : 70

Now, we have to simplify! The GCF (greatest common factor) is 7, so let's divide both numbers by 7 to maintain equality.

63/7 = 9

70/7 = 10

9 : 10 is the final answer!

9:10 bc you simplify, you have to find the GCF which is 7.
