Division Property of Equality

Step-by-step explanation:

Hi, the Division Property of Equality states that when we divide both sides of an equation by a non zero number, both sides of the equation stays the same.

In this case, we divide both sides by 9, and the equality remains the same.

9m=180

9m : 9 = 108 : 9.

m = 12
