What is x when 81 divided by x equals 61?

To find the answer, just divide the dividend by the quotient: 81 ÷ 61 = 1.327868852459

To prove this, let's compute 81 divided by 1.327868852459: $\frac{81}{1.327868852459} = 61$

How does it work?

Asking what the value of x could be when 81 divided by x gives a result of 61, is equivalent to solving the following equation:

$\frac{81}{x} = 61$

Multiply both sides by x: $\frac{81 x}{x} = 61 x$
$\frac{81 x}{x}$ is equivalent to $\frac{x}{x} \times 81$ , which simplifies to $1 \times 81$ (or just $81$ ).
Thus, the equation becomes: $81 = 61 x$
To find x, divide both sides by 61: $\frac{81}{61} = \frac{61 x}{61}$
Which gives, after simplification: $1.327868852459 = x$ (or $x = 1.327868852459$ )

So, if the dividend is 81 and the quotient is 61, the divisor is 1.327868852459.
