What is x when 87 divided by x equals 36?

To find the answer, just divide the dividend by the quotient: 87 ÷ 36 = 2.4166666666667

To prove this, let's compute 87 divided by 2.4166666666667: $\frac{87}{2.4166666666667} = 36$

How does it work?

Asking what the value of x could be when 87 divided by x gives a result of 36, is equivalent to solving the following equation:

$\frac{87}{x} = 36$

Multiply both sides by x: $\frac{87 x}{x} = 36 x$
$\frac{87 x}{x}$ is equivalent to $\frac{x}{x} \times 87$ , which simplifies to $1 \times 87$ (or just $87$ ).
Thus, the equation becomes: $87 = 36 x$
To find x, divide both sides by 36: $\frac{87}{36} = \frac{36 x}{36}$
Which gives, after simplification: $2.4166666666667 = x$ (or $x = 2.4166666666667$ )

So, if the dividend is 87 and the quotient is 36, the divisor is 2.4166666666667.
