In class 3 there are 30 pupils. There are 20 girls and 10 boys. A.What fraction of the pupils are girls? B. What fraction of the pupils are boys?
20/30
10/30
Simplify those fractions.
2/3
1/3
To find the fraction of the pupils that are girls, you need to divide the number of girls by the total number of pupils. Similarly, to find the fraction of the pupils that are boys, you need to divide the number of boys by the total number of pupils.
A. To find the fraction of girls:
Number of girls = 20
Total number of pupils = 30
Fraction of girls = Number of girls / Total number of pupils
= 20 / 30
= 2/3
Therefore, two-thirds of the pupils in class 3 are girls.
B. To find the fraction of boys:
Number of boys = 10
Total number of pupils = 30
Fraction of boys = Number of boys / Total number of pupils
= 10 / 30
= 1/3
Therefore, one-third of the pupils in class 3 are boys.
