Answer:
The ratio of boys to girls in von's class is 2:3, which means for every 2 boys there are 3 girls.
The following can represent the number of boys and girls in her class:
If there are 12 students in the class, there would be 8 boys and 4 girls (2:3 ratio)
If there are 15 students in the class, there would be 10 boys and 5 girls (2:3 ratio)
If there are 18 students in the class, there would be 12 boys and 6 girls (2:3 ratio)
And so on.
It is important to note that as long as the ratio of boys to girls is 2:3, the numbers will represent the number of boys and girls in the class.
