75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
