What is x when 22 divided by x equals 21?

To find the answer, just divide the dividend by the quotient: 22 ÷ 21 = 1.047619047619

To prove this, let's compute 22 divided by 1.047619047619: $\frac{22}{1.047619047619} = 21$

How does it work?

Asking what the value of x could be when 22 divided by x gives a result of 21, is equivalent to solving the following equation:

$\frac{22}{x} = 21$

Multiply both sides by x: $\frac{22 x}{x} = 21 x$
$\frac{22 x}{x}$ is equivalent to $\frac{x}{x} \times 22$ , which simplifies to $1 \times 22$ (or just $22$ ).
Thus, the equation becomes: $22 = 21 x$
To find x, divide both sides by 21: $\frac{22}{21} = \frac{21 x}{21}$
Which gives, after simplification: $1.047619047619 = x$ (or $x = 1.047619047619$ )

So, if the dividend is 22 and the quotient is 21, the divisor is 1.047619047619.
