2) 63

3) 10

4) 90

5) 35

6) 57

7) 195

8) 83

9) 46

10) 420

11) 102

12) 450

13) 240

Explicação passo-a-passo:

1) 800×10 = 8,000÷100 = 80 800-80 = 720

2) 90×30 =2,700÷100 = 27 90-27 = 63

3) 40×75 = 3,000÷100 = 30 40-30 = 10

4) 150×40 = 6,000÷100 = 60 150-60 = 90

5) 70×50 = 3,500÷100 = 35 70-35 = 35

6) 60×5 = 300÷100 = 3 60-3 = 57

7) 300×35 = 10,500÷100 = 105 300-105 = 195

8) 100×17 = 1,700÷100 = 17 100-17 = 83

9) 50×8 = 400÷100 = 4 50-4 = 46

10) 600×30 = 18,000 ÷ 100 = 180 600-180 = 420

11) 120×15 = 1,800÷100 = 18 120-18 = 102

12) 900×50 = 45,000÷100 = 450 900-450 = 450

13) 300×20 = 6,000÷100 = 60 300-60 = 240

espero ter ajudado!
