What is x when 79 divided by x equals 9?

To find the answer, just divide the dividend by the quotient: 79 ÷ 9 = 8.7777777777778

To prove this, let's compute 79 divided by 8.7777777777778: $\frac{79}{8.7777777777778} = 9$

How does it work?

Asking what the value of x could be when 79 divided by x gives a result of 9, is equivalent to solving the following equation:

$\frac{79}{x} = 9$

Multiply both sides by x: $\frac{79 x}{x} = 9 x$
$\frac{79 x}{x}$ is equivalent to $\frac{x}{x} \times 79$ , which simplifies to $1 \times 79$ (or just $79$ ).
Thus, the equation becomes: $79 = 9 x$
To find x, divide both sides by 9: $\frac{79}{9} = \frac{9 x}{9}$
Which gives, after simplification: $8.7777777777778 = x$ (or $x = 8.7777777777778$ )

So, if the dividend is 79 and the quotient is 9, the divisor is 8.7777777777778.
