1. Multiple choice question

Exercise condition:

4 m.

1. Closure property is not true for division of rational numbers because of the number

$0$
$1$
$-1$
$\frac{1}{2}$

$\frac{1}{2} - (\frac{3}{4} - \frac{5}{6}) \neq (\frac{1}{2} - \frac{3}{4}) - \frac{5}{6}$ illustrates that subtraction does not satisfy the ___________ property for rational numbers.

commutative
distributive
closure
associative

3. Which of the following illustrates the inverse property for addition?

$\frac{1}{8} + \frac{1}{8} = 0$
$\frac{1}{8} - \frac{1}{8} = 0$
$\frac{1}{8} - 0 = \frac{1}{8}$
$\frac{1}{8} + 0 = \frac{1}{8}$

$\frac{3}{4} \times (\frac{1}{2} - \frac{1}{4}) = \frac{3}{4} \times \frac{1}{2} - \frac{3}{4} \times \frac{1}{4}$ illustrates that multiplication is distributive over

division
addition
subtraction
multiplication
