If the farmer, his wife, his son, his daughter, and his dog all pull the turnip, and each of them contributes equally, what fraction of the total pulling force does one person contribute?
Answer
\frac{1}{5}
The correct answer is \frac{1}{5} — The fraction is \frac{1}{5}.
Step-by-step solution
- Count the number of pullers: farmer, wife, son, daughter, dog – a total of 5.
- Assume each contributes an equal share of the pulling force.
- Divide the total pulling force by 5 to find one person’s share.
- The fraction is \frac{1}{5}.
Common mistake: Ignoring the dog in the count
Concept tested: Fraction of total contribution
