What is x when 23 divided by x equals 28?

To find the answer, just divide the dividend by the quotient: 23 ÷ 28 = 0.82142857142857

To prove this, let's compute 23 divided by 0.82142857142857: $\frac{23}{0.82142857142857} = 28$

How does it work?

Asking what the value of x could be when 23 divided by x gives a result of 28, is equivalent to solving the following equation:

$\frac{23}{x} = 28$

Multiply both sides by x: $\frac{23 x}{x} = 28 x$
$\frac{23 x}{x}$ is equivalent to $\frac{x}{x} \times 23$ , which simplifies to $1 \times 23$ (or just $23$ ).
Thus, the equation becomes: $23 = 28 x$
To find x, divide both sides by 28: $\frac{23}{28} = \frac{28 x}{28}$
Which gives, after simplification: $0.82142857142857 = x$ (or $x = 0.82142857142857$ )

So, if the dividend is 23 and the quotient is 28, the divisor is 0.82142857142857.
