Answer 1

1. 6×(3+2)÷10 = 3

Work:
3+2 = 5
6 × 5 = 30
30 ÷ 10 = 3

2. 12-(3×3)+11 = 14

Work:
3 × 3 = 9
12 - 9 = 3
3 + 11 = 14

3. (10×0.4) + (10×0.8) = 12

Work:
10 × .4 = 4
10 × .8 = 8
8 + 4 = 12

4.(8 ÷ 4)×(4-2) = 4

Work:
8 ÷ 4 = 2
4 - 2 = 2
2 × 2 = 4

5.8.5-10÷2 = 3.5

Work:
10 ÷ 2 = 5
8.5 - 5 = 3.5

6.18-(8÷2)+25 = 39

Work:
8 ÷ 2 = 4
18 - 4 = 14
14 + 25 = 39
