Answer 1

Answer:

-2/3+((-4/5)+1/2)=((-2/3)+(-4/5))+1/2

Step-by-step explanation:

-2/3(-4/5+1/2)=-2/3+(-8+5/10)

=-2/3+(-3/10)

=-20-9/30

=-29/30

(-2/3-4/5)+1/2=(-10-12/15)+1/2

=-22/15+1/2

=-44+15/30

=-29/30

-2/3+((-4/5)+1/2=((-2/3)+(-4/5))+1/2

The are Associative

Answer 2

Equal

Step-by-step explanation:

Associative property

$\frac{ - 2}{3} + (( \frac{ - 4}{5} ) + \frac{1}{2} ) \: = (( \frac{ - 2}{3} ) + (\frac{ - 4}{5} )) + \frac{1}{2}$

$\frac{ - 2}{3} + \frac{ - 3}{10} \: = \frac{ - 22}{15} + \frac{1}{2}$

$\: - \frac{29}{30} \: \: \: = \: \: \: \frac{ - 29}{30}$
