What is x when 68 divided by x equals 31?

To find the answer, just divide the dividend by the quotient: 68 ÷ 31 = 2.1935483870968

To prove this, let's compute 68 divided by 2.1935483870968: $\frac{68}{2.1935483870968} = 31$

How does it work?

Asking what the value of x could be when 68 divided by x gives a result of 31, is equivalent to solving the following equation:

$\frac{68}{x} = 31$

Multiply both sides by x: $\frac{68 x}{x} = 31 x$
$\frac{68 x}{x}$ is equivalent to $\frac{x}{x} \times 68$ , which simplifies to $1 \times 68$ (or just $68$ ).
Thus, the equation becomes: $68 = 31 x$
To find x, divide both sides by 31: $\frac{68}{31} = \frac{31 x}{31}$
Which gives, after simplification: $2.1935483870968 = x$ (or $x = 2.1935483870968$ )

So, if the dividend is 68 and the quotient is 31, the divisor is 2.1935483870968.
