What is x when 64 divided by x equals 39?

To find the answer, just divide the dividend by the quotient: 64 ÷ 39 = 1.6410256410256

To prove this, let's compute 64 divided by 1.6410256410256: $\frac{64}{1.6410256410256} = 39$

How does it work?

Asking what the value of x could be when 64 divided by x gives a result of 39, is equivalent to solving the following equation:

$\frac{64}{x} = 39$

Multiply both sides by x: $\frac{64 x}{x} = 39 x$
$\frac{64 x}{x}$ is equivalent to $\frac{x}{x} \times 64$ , which simplifies to $1 \times 64$ (or just $64$ ).
Thus, the equation becomes: $64 = 39 x$
To find x, divide both sides by 39: $\frac{64}{39} = \frac{39 x}{39}$
Which gives, after simplification: $1.6410256410256 = x$ (or $x = 1.6410256410256$ )

So, if the dividend is 64 and the quotient is 39, the divisor is 1.6410256410256.
