There were a total of 32 people on the hike.
Step-by-step explanation:
Represent the number of people total by p. Then:
(5/8)p = c = the number of children
Since there are 20 children on the hike, (5/8)p must equal 20:
(5/8)p = 20
Solve for p by multiplying both sides by (8/5):
(8/5)(5/8)p = 20(8/5), or
p = 32
There were a total of 32 people on the hike.
