A 16-foot ladder leans against the side of a building. The top of the ladder touches the side of the building at 12 feet above the ground. How far away from the base of the building is the bottom of the ladder?

the least common denominator is 40

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.
