At an amusement park, 60% of the people were adults, and the rest were children. There were 720 adults. How many people were at the amusement park IN ALL?

There were 1200 people at the amusement park.

Step-by-step explanation:

Let x represent the total number of people in the amusement park.

At the amusement park, 60% of the people were adults, and the rest were children. It means that the number of people at the park that were adults would be

60/100 × x = 0.6 × x = 0.6x

There were 720 adults. It means that

0.6x = 720

Dividing the left hand side and the right hand side of the equation by 0.6, it becomes

0.6x/0.6 = 720/0.6

x = 1200
