What is x when 81 divided by x equals 32?

To find the answer, just divide the dividend by the quotient: 81 ÷ 32 = 2.53125

To prove this, let's compute 81 divided by 2.53125: $\frac{81}{2.53125} = 32$

How does it work?

Asking what the value of x could be when 81 divided by x gives a result of 32, is equivalent to solving the following equation:

$\frac{81}{x} = 32$

Multiply both sides by x: $\frac{81 x}{x} = 32 x$
$\frac{81 x}{x}$ is equivalent to $\frac{x}{x} \times 81$ , which simplifies to $1 \times 81$ (or just $81$ ).
Thus, the equation becomes: $81 = 32 x$
To find x, divide both sides by 32: $\frac{81}{32} = \frac{32 x}{32}$
Which gives, after simplification: $2.53125 = x$ (or $x = 2.53125$ )

So, if the dividend is 81 and the quotient is 32, the divisor is 2.53125.
