What is x when 26 divided by x equals 21?

To find the answer, just divide the dividend by the quotient: 26 ÷ 21 = 1.2380952380952

To prove this, let's compute 26 divided by 1.2380952380952: $\frac{26}{1.2380952380952} = 21$

How does it work?

Asking what the value of x could be when 26 divided by x gives a result of 21, is equivalent to solving the following equation:

$\frac{26}{x} = 21$

Multiply both sides by x: $\frac{26 x}{x} = 21 x$
$\frac{26 x}{x}$ is equivalent to $\frac{x}{x} \times 26$ , which simplifies to $1 \times 26$ (or just $26$ ).
Thus, the equation becomes: $26 = 21 x$
To find x, divide both sides by 21: $\frac{26}{21} = \frac{21 x}{21}$
Which gives, after simplification: $1.2380952380952 = x$ (or $x = 1.2380952380952$ )

So, if the dividend is 26 and the quotient is 21, the divisor is 1.2380952380952.
