What is x when 38 divided by x equals 86?

To find the answer, just divide the dividend by the quotient: 38 ÷ 86 = 0.44186046511628

To prove this, let's compute 38 divided by 0.44186046511628: $\frac{38}{0.44186046511628} = 86$

How does it work?

Asking what the value of x could be when 38 divided by x gives a result of 86, is equivalent to solving the following equation:

$\frac{38}{x} = 86$

Multiply both sides by x: $\frac{38 x}{x} = 86 x$
$\frac{38 x}{x}$ is equivalent to $\frac{x}{x} \times 38$ , which simplifies to $1 \times 38$ (or just $38$ ).
Thus, the equation becomes: $38 = 86 x$
To find x, divide both sides by 86: $\frac{38}{86} = \frac{86 x}{86}$
Which gives, after simplification: $0.44186046511628 = x$ (or $x = 0.44186046511628$ )

So, if the dividend is 38 and the quotient is 86, the divisor is 0.44186046511628.
