What is x when 72 divided by x equals 89?

To find the answer, just divide the dividend by the quotient: 72 ÷ 89 = 0.80898876404494

To prove this, let's compute 72 divided by 0.80898876404494: $\frac{72}{0.80898876404494} = 89$

How does it work?

Asking what the value of x could be when 72 divided by x gives a result of 89, is equivalent to solving the following equation:

$\frac{72}{x} = 89$

Multiply both sides by x: $\frac{72 x}{x} = 89 x$
$\frac{72 x}{x}$ is equivalent to $\frac{x}{x} \times 72$ , which simplifies to $1 \times 72$ (or just $72$ ).
Thus, the equation becomes: $72 = 89 x$
To find x, divide both sides by 89: $\frac{72}{89} = \frac{89 x}{89}$
Which gives, after simplification: $0.80898876404494 = x$ (or $x = 0.80898876404494$ )

So, if the dividend is 72 and the quotient is 89, the divisor is 0.80898876404494.
