2)7,85
3)35,4
4)2 6/5

Answer 2

Let's break down each expression one by one:

1. 333.66 ÷ 139.2: Result: 2.3996

2. 3.14 * 2.5: Result: 7.85

3. 30.4 * 65 + 30.4 * 35.4: Result: 1976.4 + 1076.16 = 3052.56

4. 3 1/5 - 3/5 + 4/5: Convert mixed numbers to improper fractions: 3 1/5 = 16/5 3/5 = 3/5 4/5 = 4/5

Now perform the operations: Result: (16/5) - (3/5) + (4/5) = 17/5 = 3.4

So, the final results are:

1. 2.3996
2. 7.85
3. 3052.56
4. 3.4
