What is x when 7 divided by x equals 3?

To find the answer, just divide the dividend by the quotient: 7 ÷ 3 = 2.3333333333333

To prove this, let's compute 7 divided by 2.3333333333333: $\frac{7}{2.3333333333333} = 3$

How does it work?

Asking what the value of x could be when 7 divided by x gives a result of 3, is equivalent to solving the following equation:

$\frac{7}{x} = 3$

Multiply both sides by x: $\frac{7 x}{x} = 3 x$
$\frac{7 x}{x}$ is equivalent to $\frac{x}{x} \times 7$ , which simplifies to $1 \times 7$ (or just $7$ ).
Thus, the equation becomes: $7 = 3 x$
To find x, divide both sides by 3: $\frac{7}{3} = \frac{3 x}{3}$
Which gives, after simplification: $2.3333333333333 = x$ (or $x = 2.3333333333333$ )

So, if the dividend is 7 and the quotient is 3, the divisor is 2.3333333333333.
