4. Josh knows that 3
= 2. How can he use this and knowledge of operations on positive fractions to show that 3
3
-17
• (-1)
AO3() = 3 (+ ) = 2, so by the distributive property 3 (3) must equal -1.
BO
= 3
+
= 2, so by the distributive property 3
(
must equal -1.
CO3 (3) = 2 () = 2, so by the associative property of resultiplication 3 (-) musst equal – 1.
D
= 3
- 2x
= 2. so by the associative property of multiplication 3
(6)
must equal -1.
