What is x when 13 divided by x equals 12?

To find the answer, just divide the dividend by the quotient: 13 ÷ 12 = 1.0833333333333

To prove this, let's compute 13 divided by 1.0833333333333: $\frac{13}{1.0833333333333} = 12$

How does it work?

Asking what the value of x could be when 13 divided by x gives a result of 12, is equivalent to solving the following equation:

$\frac{13}{x} = 12$

Multiply both sides by x: $\frac{13 x}{x} = 12 x$
$\frac{13 x}{x}$ is equivalent to $\frac{x}{x} \times 13$ , which simplifies to $1 \times 13$ (or just $13$ ).
Thus, the equation becomes: $13 = 12 x$
To find x, divide both sides by 12: $\frac{13}{12} = \frac{12 x}{12}$
Which gives, after simplification: $1.0833333333333 = x$ (or $x = 1.0833333333333$ )

So, if the dividend is 13 and the quotient is 12, the divisor is 1.0833333333333.
