What is x when 13 divided by x equals 82?

To find the answer, just divide the dividend by the quotient: 13 ÷ 82 = 0.15853658536585

To prove this, let's compute 13 divided by 0.15853658536585: $\frac{13}{0.15853658536585} = 82$

How does it work?

Asking what the value of x could be when 13 divided by x gives a result of 82, is equivalent to solving the following equation:

$\frac{13}{x} = 82$

Multiply both sides by x: $\frac{13 x}{x} = 82 x$
$\frac{13 x}{x}$ is equivalent to $\frac{x}{x} \times 13$ , which simplifies to $1 \times 13$ (or just $13$ ).
Thus, the equation becomes: $13 = 82 x$
To find x, divide both sides by 82: $\frac{13}{82} = \frac{82 x}{82}$
Which gives, after simplification: $0.15853658536585 = x$ (or $x = 0.15853658536585$ )

So, if the dividend is 13 and the quotient is 82, the divisor is 0.15853658536585.
