What is x when 68 divided by x equals 4?

To find the answer, just divide the dividend by the quotient: 68 ÷ 4 = 17

To prove this, let's compute 68 divided by 17: $\frac{68}{17} = 4$

How does it work?

Asking what the value of x could be when 68 divided by x gives a result of 4, is equivalent to solving the following equation:

$\frac{68}{x} = 4$

Multiply both sides by x: $\frac{68 x}{x} = 4 x$
$\frac{68 x}{x}$ is equivalent to $\frac{x}{x} \times 68$ , which simplifies to $1 \times 68$ (or just $68$ ).
Thus, the equation becomes: $68 = 4 x$
To find x, divide both sides by 4: $\frac{68}{4} = \frac{4 x}{4}$
Which gives, after simplification: $17 = x$ (or $x = 17$ )

So, if the dividend is 68 and the quotient is 4, the divisor is 17.
