The first part of the proportion would be the known values of 32 people to 128 ounces.
The second part of the proportion is X ( the number of people) for 704 ounces.
This is written as 32/128 = X/704
To solve for X Cross multiply:
32 * 704 = 128x
Simplify:
22528 = 128x
Solve for X by dividing both sides by 128:
x = 22528 / 128
x = 176 people
