6. Since D = 52, and E = 52, and 52 = 52, D must equal E. I guess the property will be the "Substitution Property of Equality"
8. This will actually come in future math, but since every term has a 1/4 in it, we can cancel it out, and you are left with GH = JK. You can also do this algebraically by actually multiplying both sides by 4. This will be the "Multiplication Property of Equality" because both numbers are being multiplied by 1/4.
I'm guessing this is what you want.
