What is x when 91 divided by x equals 49?

To find the answer, just divide the dividend by the quotient: 91 ÷ 49 = 1.8571428571429

To prove this, let's compute 91 divided by 1.8571428571429: $\frac{91}{1.8571428571429} = 49$

How does it work?

Asking what the value of x could be when 91 divided by x gives a result of 49, is equivalent to solving the following equation:

$\frac{91}{x} = 49$

Multiply both sides by x: $\frac{91 x}{x} = 49 x$
$\frac{91 x}{x}$ is equivalent to $\frac{x}{x} \times 91$ , which simplifies to $1 \times 91$ (or just $91$ ).
Thus, the equation becomes: $91 = 49 x$
To find x, divide both sides by 49: $\frac{91}{49} = \frac{49 x}{49}$
Which gives, after simplification: $1.8571428571429 = x$ (or $x = 1.8571428571429$ )

So, if the dividend is 91 and the quotient is 49, the divisor is 1.8571428571429.
