b) True

c) True

d) false

Step-by-step explanation:

Ella's grade:

Ratio of boys to girls = 3:4

Total number of boys and girls = 3+4 = 7

Since Each grade has a total of 20 girls.

Let total number of boys and girls = x

Proportion of girls: (4/7) × x = 20

4x/7 = 20

x = 35

Total number of boys and girls = 35

Number of boys = 35-20 = 15 boys

Minh's grade:

Ratio of boys to girls = 4:5

Total number of boys and girls = 4+5 = 9

Let total number of boys and girls = x

Proportion of girls: (5/9) × x = 20

5x/9 = 20

x = 36

Total number of boys and girls = 36

Number of boys = 36-20 = 16 boys

a) Ella's grade has more boys than Minh's grade.

15 boys < 16boys = boys in Ella's grade < boys in Minh's grade
