What is x when 87 divided by x equals 22?

To find the answer, just divide the dividend by the quotient: 87 ÷ 22 = 3.9545454545455

To prove this, let's compute 87 divided by 3.9545454545455: $\frac{87}{3.9545454545455} = 22$

How does it work?

Asking what the value of x could be when 87 divided by x gives a result of 22, is equivalent to solving the following equation:

$\frac{87}{x} = 22$

Multiply both sides by x: $\frac{87 x}{x} = 22 x$
$\frac{87 x}{x}$ is equivalent to $\frac{x}{x} \times 87$ , which simplifies to $1 \times 87$ (or just $87$ ).
Thus, the equation becomes: $87 = 22 x$
To find x, divide both sides by 22: $\frac{87}{22} = \frac{22 x}{22}$
Which gives, after simplification: $3.9545454545455 = x$ (or $x = 3.9545454545455$ )

So, if the dividend is 87 and the quotient is 22, the divisor is 3.9545454545455.
