What is x when 80 divided by x equals 72?

To find the answer, just divide the dividend by the quotient: 80 ÷ 72 = 1.1111111111111

To prove this, let's compute 80 divided by 1.1111111111111: $\frac{80}{1.1111111111111} = 72$

How does it work?

Asking what the value of x could be when 80 divided by x gives a result of 72, is equivalent to solving the following equation:

$\frac{80}{x} = 72$

Multiply both sides by x: $\frac{80 x}{x} = 72 x$
$\frac{80 x}{x}$ is equivalent to $\frac{x}{x} \times 80$ , which simplifies to $1 \times 80$ (or just $80$ ).
Thus, the equation becomes: $80 = 72 x$
To find x, divide both sides by 72: $\frac{80}{72} = \frac{72 x}{72}$
Which gives, after simplification: $1.1111111111111 = x$ (or $x = 1.1111111111111$ )

So, if the dividend is 80 and the quotient is 72, the divisor is 1.1111111111111.
