What is x when 92 divided by x equals 21?

To find the answer, just divide the dividend by the quotient: 92 ÷ 21 = 4.3809523809524

To prove this, let's compute 92 divided by 4.3809523809524: $\frac{92}{4.3809523809524} = 21$

How does it work?

Asking what the value of x could be when 92 divided by x gives a result of 21, is equivalent to solving the following equation:

$\frac{92}{x} = 21$

Multiply both sides by x: $\frac{92 x}{x} = 21 x$
$\frac{92 x}{x}$ is equivalent to $\frac{x}{x} \times 92$ , which simplifies to $1 \times 92$ (or just $92$ ).
Thus, the equation becomes: $92 = 21 x$
To find x, divide both sides by 21: $\frac{92}{21} = \frac{21 x}{21}$
Which gives, after simplification: $4.3809523809524 = x$ (or $x = 4.3809523809524$ )

So, if the dividend is 92 and the quotient is 21, the divisor is 4.3809523809524.
