What is x when 64 divided by x equals 12?

To find the answer, just divide the dividend by the quotient: 64 ÷ 12 = 5.3333333333333

To prove this, let's compute 64 divided by 5.3333333333333: $\frac{64}{5.3333333333333} = 12$

How does it work?

Asking what the value of x could be when 64 divided by x gives a result of 12, is equivalent to solving the following equation:

$\frac{64}{x} = 12$

Multiply both sides by x: $\frac{64 x}{x} = 12 x$
$\frac{64 x}{x}$ is equivalent to $\frac{x}{x} \times 64$ , which simplifies to $1 \times 64$ (or just $64$ ).
Thus, the equation becomes: $64 = 12 x$
To find x, divide both sides by 12: $\frac{64}{12} = \frac{12 x}{12}$
Which gives, after simplification: $5.3333333333333 = x$ (or $x = 5.3333333333333$ )

So, if the dividend is 64 and the quotient is 12, the divisor is 5.3333333333333.
