What is x when 40 divided by x equals 11?

To find the answer, just divide the dividend by the quotient: 40 ÷ 11 = 3.6363636363636

To prove this, let's compute 40 divided by 3.6363636363636: $\frac{40}{3.6363636363636} = 11$

How does it work?

Asking what the value of x could be when 40 divided by x gives a result of 11, is equivalent to solving the following equation:

$\frac{40}{x} = 11$

Multiply both sides by x: $\frac{40 x}{x} = 11 x$
$\frac{40 x}{x}$ is equivalent to $\frac{x}{x} \times 40$ , which simplifies to $1 \times 40$ (or just $40$ ).
Thus, the equation becomes: $40 = 11 x$
To find x, divide both sides by 11: $\frac{40}{11} = \frac{11 x}{11}$
Which gives, after simplification: $3.6363636363636 = x$ (or $x = 3.6363636363636$ )

So, if the dividend is 40 and the quotient is 11, the divisor is 3.6363636363636.
