What is x when 63 divided by x equals 39?

To find the answer, just divide the dividend by the quotient: 63 ÷ 39 = 1.6153846153846

To prove this, let's compute 63 divided by 1.6153846153846: $\frac{63}{1.6153846153846} = 39$

How does it work?

Asking what the value of x could be when 63 divided by x gives a result of 39, is equivalent to solving the following equation:

$\frac{63}{x} = 39$

Multiply both sides by x: $\frac{63 x}{x} = 39 x$
$\frac{63 x}{x}$ is equivalent to $\frac{x}{x} \times 63$ , which simplifies to $1 \times 63$ (or just $63$ ).
Thus, the equation becomes: $63 = 39 x$
To find x, divide both sides by 39: $\frac{63}{39} = \frac{39 x}{39}$
Which gives, after simplification: $1.6153846153846 = x$ (or $x = 1.6153846153846$ )

So, if the dividend is 63 and the quotient is 39, the divisor is 1.6153846153846.
