To prove: that division of rational number is not commutative.
Explanation of Solution
Given information:
Choose two fractions and use an area model or number line to show the division of rational numbers is not commutative.
Proof:
Choose two rational fractions as
Divide
This number line represents
And the quotient is 3.
This number line represents
Here the denominator is greater than the nominator therefore the quotient is less than 1, hence quotient in both cases is not same.
Therefore,
It is obtained that the division of rational numbers is not commutative.
