What is x when 63 divided by x equals 87?

To find the answer, just divide the dividend by the quotient: 63 ÷ 87 = 0.72413793103448

To prove this, let's compute 63 divided by 0.72413793103448: $\frac{63}{0.72413793103448} = 87$

How does it work?

Asking what the value of x could be when 63 divided by x gives a result of 87, is equivalent to solving the following equation:

$\frac{63}{x} = 87$

Multiply both sides by x: $\frac{63 x}{x} = 87 x$
$\frac{63 x}{x}$ is equivalent to $\frac{x}{x} \times 63$ , which simplifies to $1 \times 63$ (or just $63$ ).
Thus, the equation becomes: $63 = 87 x$
To find x, divide both sides by 87: $\frac{63}{87} = \frac{87 x}{87}$
Which gives, after simplification: $0.72413793103448 = x$ (or $x = 0.72413793103448$ )

So, if the dividend is 63 and the quotient is 87, the divisor is 0.72413793103448.
