Question

Amy needs to make a total of 60 deliveries this week. So far, she has completed 54 of them. What percentage of her total deliveries has Amy completed?

a) 90%
b) 15%
c) 10%
d) 20%

Answer 1

Amy has completed 90% of her total deliveries by dividing the number of completed deliveries (54) by the total (60), resulting in 0.9, and then multiplying by 100 to convert it to a percentage.

Step-by-step explanation:

To calculate what percentage of her total deliveries Amy has completed, we use the formula for percentage: (Part / Whole) × 100%. In this scenario, Amy has completed 54 deliveries out of a total of 60.

First, we divide the number of completed deliveries by the total number of deliveries: 54 / 60, which simplifies to 9 / 10 or 0.9 when calculated.

Next, we convert this fraction into a percentage by multiplying by 100: 0.9 × 100%, which equals 90%.

Therefore, Amy has completed 90% of her total deliveries, which corresponds to option a) 90%.
