Answer (1)
To find the fraction of the class that are girls and boys, we divide the number of each group by the total number of students.Girls:20/30 = 2/3So, 2/3 of the class are girls.Boys:10/30 = 1/3So, 1/3 of the class are boys.Tip: Always reduce the fraction to the lowest term by dividing the numerator and denominator by their greatest common factor (GCF).
