What is x when 57 divided by x equals 82?

To find the answer, just divide the dividend by the quotient: 57 ÷ 82 = 0.69512195121951

To prove this, let's compute 57 divided by 0.69512195121951: $\frac{57}{0.69512195121951} = 82$

How does it work?

Asking what the value of x could be when 57 divided by x gives a result of 82, is equivalent to solving the following equation:

$\frac{57}{x} = 82$

Multiply both sides by x: $\frac{57 x}{x} = 82 x$
$\frac{57 x}{x}$ is equivalent to $\frac{x}{x} \times 57$ , which simplifies to $1 \times 57$ (or just $57$ ).
Thus, the equation becomes: $57 = 82 x$
To find x, divide both sides by 82: $\frac{57}{82} = \frac{82 x}{82}$
Which gives, after simplification: $0.69512195121951 = x$ (or $x = 0.69512195121951$ )

So, if the dividend is 57 and the quotient is 82, the divisor is 0.69512195121951.
