Question 430893: Pie Chart percentage question.Thank you for taking the time to answer this question.There are 130 students. 68 like chocolate ice cream. 52 like Vanilla. I want to know what percentage like each flavor. I thought 68/130=52% and 52/130=40%
Why doesn't the total = 100%? The answer should be 57% chocolate and 43% vanilla??? How is that done? and what did I do wrong???? Thank you so much for your time and more important your knowledge.
