What is x when 11 divided by x equals 39?

To find the answer, just divide the dividend by the quotient: 11 ÷ 39 = 0.28205128205128

To prove this, let's compute 11 divided by 0.28205128205128: $\frac{11}{0.28205128205128} = 39$

How does it work?

Asking what the value of x could be when 11 divided by x gives a result of 39, is equivalent to solving the following equation:

$\frac{11}{x} = 39$

Multiply both sides by x: $\frac{11 x}{x} = 39 x$
$\frac{11 x}{x}$ is equivalent to $\frac{x}{x} \times 11$ , which simplifies to $1 \times 11$ (or just $11$ ).
Thus, the equation becomes: $11 = 39 x$
To find x, divide both sides by 39: $\frac{11}{39} = \frac{39 x}{39}$
Which gives, after simplification: $0.28205128205128 = x$ (or $x = 0.28205128205128$ )

So, if the dividend is 11 and the quotient is 39, the divisor is 0.28205128205128.
