Calculate Survey Completion: Finding Percentage of 35 out of 49 Responses

To determine the percentage of the project that Dan has completed, we'll perform the following steps:

• Step 1: Recognize the total number of survey responses that Dan has received: 35 out of 49.
• Step 2: Apply the percentage formula: $\text{Percentage Completed} = \left(\frac{35}{49}\right) \times 100\%$.
• Step 3: Calculate the fraction: $\frac{35}{49} = 0.7142857$ (approximate).
• Step 4: Convert this decimal to a percentage: $0.7142857 \times 100 \approx 71.42857\%$.
• Step 5: Round the result if necessary to obtain a whole number percentage. In this case, $71.42857\%$ rounds to $71\%$.

Therefore, the approximate percentage of the project that Dan has completed is $\textbf{71\%}$.
