What is x when 11 divided by x equals 80?

To find the answer, just divide the dividend by the quotient: 11 ÷ 80 = 0.1375

To prove this, let's compute 11 divided by 0.1375: $\frac{11}{0.1375} = 80$

How does it work?

Asking what the value of x could be when 11 divided by x gives a result of 80, is equivalent to solving the following equation:

$\frac{11}{x} = 80$

Multiply both sides by x: $\frac{11 x}{x} = 80 x$
$\frac{11 x}{x}$ is equivalent to $\frac{x}{x} \times 11$ , which simplifies to $1 \times 11$ (or just $11$ ).
Thus, the equation becomes: $11 = 80 x$
To find x, divide both sides by 80: $\frac{11}{80} = \frac{80 x}{80}$
Which gives, after simplification: $0.1375 = x$ (or $x = 0.1375$ )

So, if the dividend is 11 and the quotient is 80, the divisor is 0.1375.
