Answer 3

It looks like you have provided three different expressions in the format of "a, b: c". If I understand correctly, you want me to evaluate these expressions. To do that, I'll assume that the colon ":" represents division. Let's evaluate each expression:

1. 8 ÷ 4 = 2

2. 6 ÷ 8 = 0.75 (or 3/4)

3. 10 ÷ 5 = 2

So, the results of each expression are as follows:

1. 8,4 : 4 = 2
2. 6,8 : 2 = 0.75 (or 3/4)
3. 10,5 : 5 = 2

If you meant something else or have different instructions, please let me know, and I'll be happy to assist further!
