What value divided by 79 equals 21?

To find the answer, just multiply the divisor with the quotient: 79 × 21 = 1659

To prove this, let's compute 1659 divided by 79: $\frac{1659}{79} = 21$

How does it work?

Asking which value divided by 79 gives a result of 21 is equivalent to solving the following equation:

$\frac{x}{79} = 21$

We need to isolate x, so multiply both sides by 79: $\frac{79 x}{79} = 79 \times 21$
$\frac{79 x}{79}$ is equivalent to $\frac{79}{79} x$ , which simplifies to $1 x$ (or just $x$ ).
Thus: $x = 79 \times 21 = 1659$

So, if the divisor is 79 and the quotient is 21, the dividend is 1659.
