Ratio. Another way to work with the ratio

The legal ratio ( student per class) in Denmark is 28. The ratio in Tofthøjskolen is 24,5. Today we could see an interesting point. The are two groups of the 6th grade (12 years old), they study together in maths, English, Danish, but when they go to science (biology, physical, chemistry, and geography), music or cooking, the student are separated in three groups. Of course the ratio decreases to 14 or 15 students. Interesting point of view. Less hour but les student per class. I think It’s a good point to think.
