Question

Part A There are 30 students in a class. 17 of the students are boys. What percent of the class are girls. *

Part B If the percentages are the same throughout the grade, how many girls are in the whole seventh grade if there are 150 seventh graders? Please help me answer ;)

Answer 1

Part A: 43%

Part B: 65

Explanation:

Part A: Since there are 30 students of the class and 17 are boys, there are 13 girls. 13/30 = 43.33 = 43%.

Part B: Since 43% of the class are girls, we do 150*0.43 for the whole 7th grade which is 64.5 which I rounded to 65.
