You have the following information:

- Two-thirds (which means 2/3) of the people on a hike are adults.

- There are 36 adults

In order to calculate the number of people, you consider that 36 is 2/3 of the total people. If you name x as the total people, the number of adults is 2/3x. Thus, you can write the following algebriac expression:

2/3 x = 36

you solve the previoues equation for x. First, you multiply both sides by 3 and you divide both sides by 2.

x = 36(3/2) = 108/2 = 54

Hence, the number of people on the hike is 54
