What value divided by 18 equals 18?

How does it work?

Asking which value divided by 18 gives a result of 18 is equivalent to solving the following equation:

$\frac{x}{18}=18$

1. We need to isolate x, so multiply both sides by 18: $\frac{18x}{\mathrm{18}}=18\times 18$
2. $\frac{18x}{\mathrm{18}}$ is equivalent to $\frac{18}{\mathrm{18}}x$, which simplifies to $1x$ (or just $x$).
3. Thus: $x=18\times 18=324$

So, if the divisor is 18 and the quotient is 18, the dividend is 324.
