To find the percentage of deliveries Deandre has completed, you can use the formula:
\[ \text{Percentage of deliveries completed} = \left( \frac{\text{Number of completed deliveries}}{\text{Total deliveries needed}} \right) \times 100 \]
In Deandre's case:
- Number of completed deliveries = 34
- Total deliveries needed = 68
Now plug the numbers into the formula:
\[ \text{Percentage of deliveries completed} = \left( \frac{34}{68} \right) \times 100 \]
Calculating the fraction:
\[ \frac{34}{68} = 0.5 \]
Now multiply by 100 to convert to a percentage:
\[ 0.5 \times 100 = 50 \]
Therefore, Deandre has completed 50% of his deliveries.
