What is x when 43 divided by x equals 91?

To find the answer, just divide the dividend by the quotient: 43 ÷ 91 = 0.47252747252747

To prove this, let's compute 43 divided by 0.47252747252747: $\frac{43}{0.47252747252747} = 91$

How does it work?

Asking what the value of x could be when 43 divided by x gives a result of 91, is equivalent to solving the following equation:

$\frac{43}{x} = 91$

Multiply both sides by x: $\frac{43 x}{x} = 91 x$
$\frac{43 x}{x}$ is equivalent to $\frac{x}{x} \times 43$ , which simplifies to $1 \times 43$ (or just $43$ ).
Thus, the equation becomes: $43 = 91 x$
To find x, divide both sides by 91: $\frac{43}{91} = \frac{91 x}{91}$
Which gives, after simplification: $0.47252747252747 = x$ (or $x = 0.47252747252747$ )

So, if the dividend is 43 and the quotient is 91, the divisor is 0.47252747252747.
