Numerator of a fraction that has a square root in it (but you don’t have to simplify the denominator with the square root) I always thought what you do to the top you must do to the bottom

75 tickets have been sold so far.

step-by-step explanation:

⇒ x = 75

therefore 75 tickets have been sold so far.
