for use after Bits and Pieces III Investigation 4As you work with operations on rational numbers, you may notice certaincharacteristics that hold true.
Therefore, a 9.
B.
25 3 (4 3 12) ?3 (4 3 k) 3 12 ?3
Use the Associative Property of Multiplication to regroup themultiplication, so 25 3 (4 3 12) ?3 (25 3 4) 3 12 ?3.
Use the
Commutative Property of Multiplication to reorder the multiplication,so (25 3 4) 3 12 ?3 5 (4 3 25) 3 12 ?3.
So, k 5 25. The rectangle area is 3(4 ?6) = 3(10),or 30. These rules are
described by the properties of rational numbers. During Example 10.1, ask: • Is the order of the terms different on the ...
