What is x when 81 divided by x equals 29?

To find the answer, just divide the dividend by the quotient: 81 ÷ 29 = 2.7931034482759

To prove this, let's compute 81 divided by 2.7931034482759: $\frac{81}{2.7931034482759} = 29$

How does it work?

Asking what the value of x could be when 81 divided by x gives a result of 29, is equivalent to solving the following equation:

$\frac{81}{x} = 29$

Multiply both sides by x: $\frac{81 x}{x} = 29 x$
$\frac{81 x}{x}$ is equivalent to $\frac{x}{x} \times 81$ , which simplifies to $1 \times 81$ (or just $81$ ).
Thus, the equation becomes: $81 = 29 x$
To find x, divide both sides by 29: $\frac{81}{29} = \frac{29 x}{29}$
Which gives, after simplification: $2.7931034482759 = x$ (or $x = 2.7931034482759$ )

So, if the dividend is 81 and the quotient is 29, the divisor is 2.7931034482759.
