What is x when 100 divided by x equals 23?

To find the answer, just divide the dividend by the quotient: 100 ÷ 23 = 4.3478260869565

To prove this, let's compute 100 divided by 4.3478260869565: $\frac{100}{4.3478260869565} = 23$

How does it work?

Asking what the value of x could be when 100 divided by x gives a result of 23, is equivalent to solving the following equation:

$\frac{100}{x} = 23$

Multiply both sides by x: $\frac{100 x}{x} = 23 x$
$\frac{100 x}{x}$ is equivalent to $\frac{x}{x} \times 100$ , which simplifies to $1 \times 100$ (or just $100$ ).
Thus, the equation becomes: $100 = 23 x$
To find x, divide both sides by 23: $\frac{100}{23} = \frac{23 x}{23}$
Which gives, after simplification: $4.3478260869565 = x$ (or $x = 4.3478260869565$ )

So, if the dividend is 100 and the quotient is 23, the divisor is 4.3478260869565.
