What is x when 81 divided by x equals 69?

To find the answer, just divide the dividend by the quotient: 81 ÷ 69 = 1.1739130434783

To prove this, let's compute 81 divided by 1.1739130434783: $\frac{81}{1.1739130434783} = 69$

How does it work?

Asking what the value of x could be when 81 divided by x gives a result of 69, is equivalent to solving the following equation:

$\frac{81}{x} = 69$

Multiply both sides by x: $\frac{81 x}{x} = 69 x$
$\frac{81 x}{x}$ is equivalent to $\frac{x}{x} \times 81$ , which simplifies to $1 \times 81$ (or just $81$ ).
Thus, the equation becomes: $81 = 69 x$
To find x, divide both sides by 69: $\frac{81}{69} = \frac{69 x}{69}$
Which gives, after simplification: $1.1739130434783 = x$ (or $x = 1.1739130434783$ )

So, if the dividend is 81 and the quotient is 69, the divisor is 1.1739130434783.
