What is x when 12 divided by x equals 71?

To find the answer, just divide the dividend by the quotient: 12 ÷ 71 = 0.16901408450704

To prove this, let's compute 12 divided by 0.16901408450704: $\frac{12}{0.16901408450704} = 71$

How does it work?

Asking what the value of x could be when 12 divided by x gives a result of 71, is equivalent to solving the following equation:

$\frac{12}{x} = 71$

Multiply both sides by x: $\frac{12 x}{x} = 71 x$
$\frac{12 x}{x}$ is equivalent to $\frac{x}{x} \times 12$ , which simplifies to $1 \times 12$ (or just $12$ ).
Thus, the equation becomes: $12 = 71 x$
To find x, divide both sides by 71: $\frac{12}{71} = \frac{71 x}{71}$
Which gives, after simplification: $0.16901408450704 = x$ (or $x = 0.16901408450704$ )

So, if the dividend is 12 and the quotient is 71, the divisor is 0.16901408450704.
