Division is not commutative. Refer to the step-by-step part below for the explanation.

Work Step by Step

Division is not commutative because for most real numbers $a$ and $b$, $a \div b \ne b \div a.$ To illustrate, let $a=4$ and $b=2$. Then, $a \div b = 4 \div 2 = 2$ while $b \div a = 2 \div 4 = \frac{1}{2}$ Note that $a \div b \ne b \div a$ Thus, division is not commutative.
