One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do

since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get

, which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.

10% of 120 = 12
12 x 7 = 84
70% = 84
120 x 70 = 8400
8400 / 100 = 84
It’s either showing you that both sides of the equation equal to the same thing or that you can find 70% of 120 by using the steps on the right
