What is x when 57 divided by x equals 73?

To find the answer, just divide the dividend by the quotient: 57 ÷ 73 = 0.78082191780822

To prove this, let's compute 57 divided by 0.78082191780822: $\frac{57}{0.78082191780822} = 73$

How does it work?

Asking what the value of x could be when 57 divided by x gives a result of 73, is equivalent to solving the following equation:

$\frac{57}{x} = 73$

Multiply both sides by x: $\frac{57 x}{x} = 73 x$
$\frac{57 x}{x}$ is equivalent to $\frac{x}{x} \times 57$ , which simplifies to $1 \times 57$ (or just $57$ ).
Thus, the equation becomes: $57 = 73 x$
To find x, divide both sides by 73: $\frac{57}{73} = \frac{73 x}{73}$
Which gives, after simplification: $0.78082191780822 = x$ (or $x = 0.78082191780822$ )

So, if the dividend is 57 and the quotient is 73, the divisor is 0.78082191780822.
