What is x when 39 divided by x equals 71?

To find the answer, just divide the dividend by the quotient: 39 ÷ 71 = 0.54929577464789

To prove this, let's compute 39 divided by 0.54929577464789: $\frac{39}{0.54929577464789} = 71$

How does it work?

Asking what the value of x could be when 39 divided by x gives a result of 71, is equivalent to solving the following equation:

$\frac{39}{x} = 71$

Multiply both sides by x: $\frac{39 x}{x} = 71 x$
$\frac{39 x}{x}$ is equivalent to $\frac{x}{x} \times 39$ , which simplifies to $1 \times 39$ (or just $39$ ).
Thus, the equation becomes: $39 = 71 x$
To find x, divide both sides by 71: $\frac{39}{71} = \frac{71 x}{71}$
Which gives, after simplification: $0.54929577464789 = x$ (or $x = 0.54929577464789$ )

So, if the dividend is 39 and the quotient is 71, the divisor is 0.54929577464789.
