What is x when 40 divided by x equals 52?

To find the answer, just divide the dividend by the quotient: 40 ÷ 52 = 0.76923076923077

To prove this, let's compute 40 divided by 0.76923076923077: $\frac{40}{0.76923076923077} = 52$

How does it work?

Asking what the value of x could be when 40 divided by x gives a result of 52, is equivalent to solving the following equation:

$\frac{40}{x} = 52$

Multiply both sides by x: $\frac{40 x}{x} = 52 x$
$\frac{40 x}{x}$ is equivalent to $\frac{x}{x} \times 40$ , which simplifies to $1 \times 40$ (or just $40$ ).
Thus, the equation becomes: $40 = 52 x$
To find x, divide both sides by 52: $\frac{40}{52} = \frac{52 x}{52}$
Which gives, after simplification: $0.76923076923077 = x$ (or $x = 0.76923076923077$ )

So, if the dividend is 40 and the quotient is 52, the divisor is 0.76923076923077.
