What is x when 42 divided by x equals 23?

To find the answer, just divide the dividend by the quotient: 42 ÷ 23 = 1.8260869565217

To prove this, let's compute 42 divided by 1.8260869565217: $\frac{42}{1.8260869565217} = 23$

How does it work?

Asking what the value of x could be when 42 divided by x gives a result of 23, is equivalent to solving the following equation:

$\frac{42}{x} = 23$

Multiply both sides by x: $\frac{42 x}{x} = 23 x$
$\frac{42 x}{x}$ is equivalent to $\frac{x}{x} \times 42$ , which simplifies to $1 \times 42$ (or just $42$ ).
Thus, the equation becomes: $42 = 23 x$
To find x, divide both sides by 23: $\frac{42}{23} = \frac{23 x}{23}$
Which gives, after simplification: $1.8260869565217 = x$ (or $x = 1.8260869565217$ )

So, if the dividend is 42 and the quotient is 23, the divisor is 1.8260869565217.
