Question

Explain why 0 divided by 7 =0, but 7 divided by 0 does not exsist

Answer 1

$\frac{0}{7} = 0$$[\frac{0}{x} =0 ]$

0 divided by any number will equal to 0 and has meaning.

$\frac{7}{0} =0$. $[ \frac{x}{0} = 0 ]$

the expression has no meaning. any number divided by 0 is undefined.

Answer 2

$\frac{0}{7}$ = 0     [ apply $\frac{0}{a}=0$ rule ] as 0 divided by any number will equal to 0 and has meaning.

$\frac{7}{0}$ = undefined.   [ apply $\frac{a}{0}\:\mathr$ = undefined rule ]  as the expression has no meaning. any number divided by 0 is undefined.
