What value divided by 79 equals 81?

To find the answer, just multiply the divisor with the quotient: 79 × 81 = 6399

To prove this, let's compute 6399 divided by 79: $\frac{6399}{79} = 81$

How does it work?

Asking which value divided by 79 gives a result of 81 is equivalent to solving the following equation:

$\frac{x}{79} = 81$

We need to isolate x, so multiply both sides by 79: $\frac{79 x}{79} = 79 \times 81$
$\frac{79 x}{79}$ is equivalent to $\frac{79}{79} x$ , which simplifies to $1 x$ (or just $x$ ).
Thus: $x = 79 \times 81 = 6399$

So, if the divisor is 79 and the quotient is 81, the dividend is 6399.
