Answer 2

4. 3/4 × 1  2/3 = 3/4 × 5/3 = 15/12 = 1, 20
5. 4,35 + 6,8 = 11, 15
6.  4/5 ÷ 1/2 = 1 4/5
7.  4/6 × 1/4 ÷ 1/2 = 1/2
8. 2 1/2 - 4/5 = 2 3/10
9. 6000 × 4 = 24.000 × 2 = 48. 000
10. 15/4 = 15 ÷ 4 = 3 1/4
11. [ 10 3/4 ] = 43/4 + [ 6 1/2 ] = 13/2 ... 43/4 + 26/4
12. 24,25 + 6 1/2 - 25% = 40 1/3
13. 6/8 × 2 1/2 = 1,33 × 2,5 = 1, 125
14. 25.000 - 30% = 7.500 - 10% = 750
15. 11,45 + 0,03 = 11,48 - 6,4 = 5,08
16. 3.000 - 1/6 = 2.999
17. 8 1/2 - 2,5 - 40% = 10,66
18. 40.000 - 20% = 46. 000
