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.
now let's assume the total number of tickets sold be x.
then 60% of x = 45
⇒ ![x\frac{60}{100}=45](/tex.php?f=x\frac{60}{100}=45)
⇒ x(.6) = 45
by dividing with .6 on both the sides of the equation
![\frac{x(.6)}{(.6)}= \frac{45}{(.6)}](/tex.php?f=\frac{x(.6)}{(.6)}= \frac{45}{(.6)})
⇒ x = 75
therefore 75 tickets have been sold so far.
