Question

Show that a whole number divided by $0$ is not defined. Give two suitable examples.

Answer 1

Division by a number means subtracting that number repeatedly until we reach zero.

Eg $1$:

Let us find $8÷2$

So, according to above mentioned rule.

$8-2=6$. ……..$\left(1\right)$

$6-2=4$ ……. .$\left(2\right)$

$4-2=2$. …..…$\left(3\right)$

$2-2=0$.. …… $\left(4\right)$

So, here we find that after $4$ moves we reach $0$.

Similarly,

Eg $2$: Let us now try$8÷0$

$8-0=8$……… .$\left(1\right)$

$8-0=8$ ……… $\left(2\right)$

$8-0=8$………..$\left(3\right)$

$8-0=8$………..$\left(4\right)$

In every move we get $8$ again and this will never stop.

Thus, a whole number divided by $0$ is not defined.
