Commutative and Associative Properties

EXAMPLE 7.6

Use the associative properties to rewrite the following:

(a) \((3+0.6)+0.4=\) ________

(b) \(\left(-4 \cdot \frac{2}{5}\right) \cdot 15=\) ________

Try It 7.11

Use the associative properties to rewrite the following:

(a) \((1+0.7)+0.3= \text{________} \)
(b) \((-9 \cdot 8) \cdot \frac{3}{4}= \text{________} \)

Try It 7.12

Use the associative properties to rewrite the following:

(a) \((4+0.6)+0.4= \text{________}\)
(b) \((-2 \cdot 12) \cdot \frac{5}{6}= \text{________}\)
