What is x when 75 divided by x equals 91?

To find the answer, just divide the dividend by the quotient: 75 ÷ 91 = 0.82417582417582

To prove this, let's compute 75 divided by 0.82417582417582: $\frac{75}{0.82417582417582} = 91$

How does it work?

Asking what the value of x could be when 75 divided by x gives a result of 91, is equivalent to solving the following equation:

$\frac{75}{x} = 91$

Multiply both sides by x: $\frac{75 x}{x} = 91 x$
$\frac{75 x}{x}$ is equivalent to $\frac{x}{x} \times 75$ , which simplifies to $1 \times 75$ (or just $75$ ).
Thus, the equation becomes: $75 = 91 x$
To find x, divide both sides by 91: $\frac{75}{91} = \frac{91 x}{91}$
Which gives, after simplification: $0.82417582417582 = x$ (or $x = 0.82417582417582$ )

So, if the dividend is 75 and the quotient is 91, the divisor is 0.82417582417582.
