Answer:
Amount of peanut butter each student get = 533.34 gram (Approx.)
Step-by-step explanation:
Given:
Amount of peanut butter Mr black has = 32 kg
Total number of students = 60 students
Find:
Amount of peanut butter each student get
Computation:
Amount of peanut butter Mr black has = 32 kg
Amount of peanut butter Mr black has = 32 x 1,000 gram
Amount of peanut butter Mr black has = 32,000 gram

Amount of peanut butter each student get = 32,000 / 60
Amount of peanut butter each student get = 533.33
Amount of peanut butter each student get = 533.34 gram (Approx.)

After 1 hr, .... project is done.
In other words,
2/3 of project ---- 3/4 hours
? of project ------ 1 hour
The more Katie works, the more the project nears completion. This is a direct proportionality kind of relationship.
Therefore,
Part of project completed in 1 hour = (2/3*1)/(3/4) = 2/3*4/3 = 8/9
