Name the Algebraic Property Being Used. 1. 6 + 1y = 6 + y
2. (4x + 9)(-2) = -8x - 18
3. (9c)(5d)(0) = 0

10:40

Step-by-step explanation:

I believe the answer would be 10/40. First, I simplified all of the given rations. You do this by finding the two numbers greatest common factor. For example, 3/12, 3 goes into 3 once and 3 goes into 12 four times. So that ratio would be 1/4. If you continue the pattern you would get 1/4 for all of them. Therefore, 10/40 would be correct since it's ratio would also be 1/4.
