Answer 1

1) 0,024•4, 5=0, 108
2) 29,41•1000=29410
3) 2,86: 100=0, 0286
4) 4: 16=0, 25
5) 0,48: 0,8=0, 6
6) 9,1: 0,07=130

Answer 2

Let's solve the given mathematical expressions step by step:

1. 0,024 ∙ 4,5: Multiplying 0.024 by 4.5, we get: 0.024 * 4.5 = 0.108.

2. 2,86 : 100: Dividing 2.86 by 100, we get: 2.86 / 100 = 0.0286.

3. 0,48 : 0,8: Dividing 0.48 by 0.8, we get: 0.48 / 0.8 = 0.6.

4. 4 : 16: Dividing 4 by 16, we get: 4 / 16 = 0.25.

5. 29.41 ∙ 1,000: Multiplying 29.41 by 1,000, we get: 29.41 * 1,000 = 29,410.

6. 9.1 : 0.07: Dividing 9.1 by 0.07, we get: 9.1 / 0.07 = 130.

So, the results are:

1. 0,024 ∙ 4,5 = 0,108
2. 2,86 : 100 = 0,0286
3. 0,48 : 0,8 = 0,6
4. 4 : 16 = 0,25
5. 29,41 ∙ 1 000 = 29 410
6. 9,1 : 0,07 = 130
