Round off:

11.) 10.06 x 8 = 80

10.06 = 10

8 = 8

10 × 8 = 80

----------------------------

12.) 1.07 x 3 = 3

1.07 = 1

3 = 3

1 × 3 = 3

----------------------------

13.) 9 x 6.04 = 54

9 = 9

6.04 = 6

9 × 6 = 54

----------------------------

14.) 6 x 3.05 = 18

6 = 6

3.05 = 3

6 × 3 = 18

----------------------------

15.) 31 x 5.12 = 150

31 = 30
