What is x when 44 divided by x equals 21?

To find the answer, just divide the dividend by the quotient: 44 ÷ 21 = 2.0952380952381

To prove this, let's compute 44 divided by 2.0952380952381: $\frac{44}{2.0952380952381} = 21$

How does it work?

Asking what the value of x could be when 44 divided by x gives a result of 21, is equivalent to solving the following equation:

$\frac{44}{x} = 21$

Multiply both sides by x: $\frac{44 x}{x} = 21 x$
$\frac{44 x}{x}$ is equivalent to $\frac{x}{x} \times 44$ , which simplifies to $1 \times 44$ (or just $44$ ).
Thus, the equation becomes: $44 = 21 x$
To find x, divide both sides by 21: $\frac{44}{21} = \frac{21 x}{21}$
Which gives, after simplification: $2.0952380952381 = x$ (or $x = 2.0952380952381$ )

So, if the dividend is 44 and the quotient is 21, the divisor is 2.0952380952381.
