Answer:
a. To find the ratio of boys to girls, we divide the number of boys by the number of girls.
Ratio of boys to girls = 12 boys / 30 girls
= 2/5
Therefore, the ratio of boys to girls is 2:5.
b. To find the ratio of girls to boys, we divide the number of girls by the number of boys.
Ratio of girls to boys = 30 girls / 12 boys
= 5/2
Therefore, the ratio of girls to boys is 5:2.
c. To find the ratio of boys to the class, we divide the number of boys by the total number of students in the class.
Ratio of boys to class = 12 boys / (30 girls + 12 boys)
= 12/42
= 2/7
Therefore, the ratio of boys to the class is 2:7.
d. To find the ratio of girls to the class, we divide the number of girls by the total number of students in the class.
Ratio of girls to class = 30 girls / (30 girls + 12 boys)
= 30/42
= 5/7
Therefore, the ratio of girls to the class is 5:7.
In summary:
a. Boys to girls ratio: 2:5
b. Girls to boys ratio: 5:2
c. Boys to class ratio: 2:7
d. Girls to class ratio: 5:7
