28/24 = 1 4/24  or 1 1/6

to simplify the answer you divide the denominator into the numerator and get 1 4/24

then reduce 4/24 by dividing the greatest common multiple into the numerator and the denominator to reduce the fraction to the lowest terms  so 4/24 = 1/6   when it is divided by 4

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(.6) = 45

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

⇒ x = 75

therefore 75 tickets have been sold so far.
