Learn how to solve problems about workers, machines, and pipes completing jobs together!
What Are Work Problems?
Work problems are math problems about completing tasks or jobs. These tasks can be done by:
👷
Workers
People doing jobs
🚜
Machines
Tractors, printers
🚰
Pipes
Filling tanks
🏭
Factories
Making products
🎯 The main questions we answer:
- How long does it take to complete a job?
- How fast does someone work? (their rate)
- How much work gets done in a certain time?
💡 The Big Idea: The Whole Work = 1
In work problems, we always say the entire job equals 1 (one complete job).
It doesn't matter what the work is:
- Painting a house = 1
- Filling a swimming pool = 1
- Plowing a field = 1
- Making 100 parts = 1
The complete job is always 1!
