What is x when 86 divided by x equals 72?

To find the answer, just divide the dividend by the quotient: 86 ÷ 72 = 1.1944444444444

To prove this, let's compute 86 divided by 1.1944444444444: $\frac{86}{1.1944444444444} = 72$

How does it work?

Asking what the value of x could be when 86 divided by x gives a result of 72, is equivalent to solving the following equation:

$\frac{86}{x} = 72$

Multiply both sides by x: $\frac{86 x}{x} = 72 x$
$\frac{86 x}{x}$ is equivalent to $\frac{x}{x} \times 86$ , which simplifies to $1 \times 86$ (or just $86$ ).
Thus, the equation becomes: $86 = 72 x$
To find x, divide both sides by 72: $\frac{86}{72} = \frac{72 x}{72}$
Which gives, after simplification: $1.1944444444444 = x$ (or $x = 1.1944444444444$ )

So, if the dividend is 86 and the quotient is 72, the divisor is 1.1944444444444.
