Final answer:
To find the percentage of brown Reese's pieces, divide the number of brown candies (10) by the total number of candies (13) and multiply by 100, resulting in approximately 76.92% brown candies.
Step-by-step explanation:
The question asks us to find the percentage of brown candies if there are three orange and ten brown Reese's pieces. To find the percentage, we first need to calculate the total number of candies, which is the sum of orange and brown candies: 3 (orange) + 10 (brown) = 13 candies in total. The percentage of brown candies is found by dividing the number of brown candies by the total number of candies and then multiplying by 100 to convert it to a percentage.
Percentage of brown candies = (Number of brown candies / Total number of candies) × 100
So, we have:
Percentage of brown candies = (10 / 13) × 100 ≈ 76.92%
Therefore, the percentage of brown Reese's pieces is approximately 76.92%.
