Approximately, 618.42

Explanation:

Assume an unknown quantity is X.
Then 19% (or 0.19) of this quantity is 117.5.

Therefore, we can represent it in an equation:
0.19 * X = 117.5

To solve this equation, recall that both sides of an equation can be divided by the same number not equal to 0 and get a new equation.
Let's divide both sides of our equation by 0.19:

(0.19*X)/0.19 = 117.5/0.19

which can be transformed into
X*0.19/0.19 = 117.5/0.19

or, since 0.19/0.19=1 and 117.5/0.19~~618.42,

X ~~ 618.42
