What is x when 63 divided by x equals 75?

To find the answer, just divide the dividend by the quotient: 63 ÷ 75 = 0.84

To prove this, let's compute 63 divided by 0.84: $\frac{63}{0.84} = 75$

How does it work?

Asking what the value of x could be when 63 divided by x gives a result of 75, is equivalent to solving the following equation:

$\frac{63}{x} = 75$

Multiply both sides by x: $\frac{63 x}{x} = 75 x$
$\frac{63 x}{x}$ is equivalent to $\frac{x}{x} \times 63$ , which simplifies to $1 \times 63$ (or just $63$ ).
Thus, the equation becomes: $63 = 75 x$
To find x, divide both sides by 75: $\frac{63}{75} = \frac{75 x}{75}$
Which gives, after simplification: $0.84 = x$ (or $x = 0.84$ )

So, if the dividend is 63 and the quotient is 75, the divisor is 0.84.
