What value divided by 13 equals 81?

To find the answer, just multiply the divisor with the quotient: 13 × 81 = 1053

To prove this, let's compute 1053 divided by 13: $\frac{1053}{13} = 81$

How does it work?

Asking which value divided by 13 gives a result of 81 is equivalent to solving the following equation:

$\frac{x}{13} = 81$

We need to isolate x, so multiply both sides by 13: $\frac{13 x}{13} = 13 \times 81$
$\frac{13 x}{13}$ is equivalent to $\frac{13}{13} x$ , which simplifies to $1 x$ (or just $x$ ).
Thus: $x = 13 \times 81 = 1053$

So, if the divisor is 13 and the quotient is 81, the dividend is 1053.
