What is x when 12 divided by x equals 66?

To find the answer, just divide the dividend by the quotient: 12 ÷ 66 = 0.18181818181818

To prove this, let's compute 12 divided by 0.18181818181818: $\frac{12}{0.18181818181818} = 66$

How does it work?

Asking what the value of x could be when 12 divided by x gives a result of 66, is equivalent to solving the following equation:

$\frac{12}{x} = 66$

Multiply both sides by x: $\frac{12 x}{x} = 66 x$
$\frac{12 x}{x}$ is equivalent to $\frac{x}{x} \times 12$ , which simplifies to $1 \times 12$ (or just $12$ ).
Thus, the equation becomes: $12 = 66 x$
To find x, divide both sides by 66: $\frac{12}{66} = \frac{66 x}{66}$
Which gives, after simplification: $0.18181818181818 = x$ (or $x = 0.18181818181818$ )

So, if the dividend is 12 and the quotient is 66, the divisor is 0.18181818181818.
