In a jar there are 3 yellow candies, 3 blue candies, and 2 orange candies. What percent of the jar is filled with orange candies
Nastasia [14]

Answer: 25 percent of the jar is filled with orange candies

Step-by-step explanation:

number of orange candies/total number of candies × 100

2/8 × 100 = 25%
