1. Determine individual rates of work:
\text{Monice's rate} = \frac{1}{5} \text{ fence per day}
\text{Mike's rate} = \frac{1}{4} \text{ fence per day}
2. Combine rates of work:
\frac{1}{T} = \frac{1}{5} + \frac{1}{4}
\frac{1}{T} = \frac{4}{20} + \frac{5}{20}
\frac{1}{T} = \frac{9}{20}
3. Solve for \( T \):
T = \frac{20}{9}
4. Simplify to a mixed number:
T = 2 \, \frac{2}{9} \text{ days}
5. Approximate value:
T \approx 2.22 \text{ days}
The answer is: T = 2 \, \frac{2}{9} \text{ days}
2. Combine rates of work:
3. Solve for \( T \):
4. Simplify to a mixed number:
5. Approximate value:
