What is x when 40 divided by x equals 49?

To find the answer, just divide the dividend by the quotient: 40 ÷ 49 = 0.81632653061224

To prove this, let's compute 40 divided by 0.81632653061224: $\frac{40}{0.81632653061224} = 49$

How does it work?

Asking what the value of x could be when 40 divided by x gives a result of 49, is equivalent to solving the following equation:

$\frac{40}{x} = 49$

Multiply both sides by x: $\frac{40 x}{x} = 49 x$
$\frac{40 x}{x}$ is equivalent to $\frac{x}{x} \times 40$ , which simplifies to $1 \times 40$ (or just $40$ ).
Thus, the equation becomes: $40 = 49 x$
To find x, divide both sides by 49: $\frac{40}{49} = \frac{49 x}{49}$
Which gives, after simplification: $0.81632653061224 = x$ (or $x = 0.81632653061224$ )

So, if the dividend is 40 and the quotient is 49, the divisor is 0.81632653061224.
