What is x when 5 divided by x equals 86?

To find the answer, just divide the dividend by the quotient: 5 ÷ 86 = 0.058139534883721

To prove this, let's compute 5 divided by 0.058139534883721: $\frac{5}{0.058139534883721} = 86$

How does it work?

Asking what the value of x could be when 5 divided by x gives a result of 86, is equivalent to solving the following equation:

$\frac{5}{x} = 86$

Multiply both sides by x: $\frac{5 x}{x} = 86 x$
$\frac{5 x}{x}$ is equivalent to $\frac{x}{x} \times 5$ , which simplifies to $1 \times 5$ (or just $5$ ).
Thus, the equation becomes: $5 = 86 x$
To find x, divide both sides by 86: $\frac{5}{86} = \frac{86 x}{86}$
Which gives, after simplification: $0.058139534883721 = x$ (or $x = 0.058139534883721$ )

So, if the dividend is 5 and the quotient is 86, the divisor is 0.058139534883721.
