What value divided by 11 equals 21?

To find the answer, just multiply the divisor with the quotient: 11 × 21 = 231

To prove this, let's compute 231 divided by 11: $\frac{231}{11} = 21$

How does it work?

Asking which value divided by 11 gives a result of 21 is equivalent to solving the following equation:

$\frac{x}{11} = 21$

We need to isolate x, so multiply both sides by 11: $\frac{11 x}{11} = 11 \times 21$
$\frac{11 x}{11}$ is equivalent to $\frac{11}{11} x$ , which simplifies to $1 x$ (or just $x$ ).
Thus: $x = 11 \times 21 = 231$

So, if the divisor is 11 and the quotient is 21, the dividend is 231.
