What is x when 64 divided by x equals 18?

To find the answer, just divide the dividend by the quotient: 64 ÷ 18 = 3.5555555555556

To prove this, let's compute 64 divided by 3.5555555555556: $\frac{64}{3.5555555555556} = 18$

How does it work?

Asking what the value of x could be when 64 divided by x gives a result of 18, is equivalent to solving the following equation:

$\frac{64}{x} = 18$

Multiply both sides by x: $\frac{64 x}{x} = 18 x$
$\frac{64 x}{x}$ is equivalent to $\frac{x}{x} \times 64$ , which simplifies to $1 \times 64$ (or just $64$ ).
Thus, the equation becomes: $64 = 18 x$
To find x, divide both sides by 18: $\frac{64}{18} = \frac{18 x}{18}$
Which gives, after simplification: $3.5555555555556 = x$ (or $x = 3.5555555555556$ )

So, if the dividend is 64 and the quotient is 18, the divisor is 3.5555555555556.
