What value divided by 25 equals 81?

How does it work?

Asking which value divided by 25 gives a result of 81 is equivalent to solving the following equation:

$\frac{x}{25}=81$

1. We need to isolate x, so multiply both sides by 25: $\frac{25x}{\mathrm{25}}=25\times 81$
2. $\frac{25x}{\mathrm{25}}$ is equivalent to $\frac{25}{\mathrm{25}}x$, which simplifies to $1x$ (or just $x$).
3. Thus: $x=25\times 81=2025$

So, if the divisor is 25 and the quotient is 81, the dividend is 2025.
