Verify the associative property of addition for the given rational number.

$\frac{7}{15}, \frac{-4}{5},\frac{2}{3}$

If $a=\frac{-4}{7}, b=\frac{2}{21},$ and $c=\frac{1}{3}$ then check that $\left(a-b\right)-c\ne a-(b-c)$

Find the sum of the additive inverse of $\frac{4}{9}$ and $\frac{-2}{3}$

If we add a rational number to its additive inverse, then we will get:

The expression $x\times y=y\times x$ represents the following property of the rational numbers;

All rational numbers are closed under
