What is x when 46 divided by x equals 81?

To find the answer, just divide the dividend by the quotient: 46 ÷ 81 = 0.5679012345679

To prove this, let's compute 46 divided by 0.5679012345679: $\frac{46}{0.5679012345679} = 81$

How does it work?

Asking what the value of x could be when 46 divided by x gives a result of 81, is equivalent to solving the following equation:

$\frac{46}{x} = 81$

Multiply both sides by x: $\frac{46 x}{x} = 81 x$
$\frac{46 x}{x}$ is equivalent to $\frac{x}{x} \times 46$ , which simplifies to $1 \times 46$ (or just $46$ ).
Thus, the equation becomes: $46 = 81 x$
To find x, divide both sides by 81: $\frac{46}{81} = \frac{81 x}{81}$
Which gives, after simplification: $0.5679012345679 = x$ (or $x = 0.5679012345679$ )

So, if the dividend is 46 and the quotient is 81, the divisor is 0.5679012345679.
