Answer 1

$4) \: 0.8 \times 5 = 4 \\ 5) \: 0.7 \times 3 = 2.1 \\ 6) \: 0.3 \times 25 = 7.5 \\ 7) \: (1.7 + 2) \times 4 = 3.7 \times 4 = 14.8 \\ 8) \: (5.3 + 1.4) \times 3 = 6.7 \times 3 = 20.1 \\ 9) \: (6.15 + 3.5) \times 5 = 9.65 \times 5 = 48.25$

Answer 2

4. 0,8 * 5 = 4
5. 0,7 * 3 = 2,1
6. 0,3 * 25 = 7,5
7. (1,7 + 2) * 4 = 9,4
8. (5,3 + 1,4) * 3 = 19,5
9. (6,15 + 3,5) * 5 = 97,25
