What is x when 31 divided by x equals 53?

To find the answer, just divide the dividend by the quotient: 31 ÷ 53 = 0.58490566037736

To prove this, let's compute 31 divided by 0.58490566037736: $\frac{31}{0.58490566037736} = 53$

How does it work?

Asking what the value of x could be when 31 divided by x gives a result of 53, is equivalent to solving the following equation:

$\frac{31}{x} = 53$

Multiply both sides by x: $\frac{31 x}{x} = 53 x$
$\frac{31 x}{x}$ is equivalent to $\frac{x}{x} \times 31$ , which simplifies to $1 \times 31$ (or just $31$ ).
Thus, the equation becomes: $31 = 53 x$
To find x, divide both sides by 53: $\frac{31}{53} = \frac{53 x}{53}$
Which gives, after simplification: $0.58490566037736 = x$ (or $x = 0.58490566037736$ )

So, if the dividend is 31 and the quotient is 53, the divisor is 0.58490566037736.
