me ajudem é de matemática​

Answer 1

Explicação passo-a-passo:

20% × 40 = 20 × 40/100 = 800/100 = 8

30% × 60 = 30 × 60/100 = 1800/100 = 18

10% × 20 = 10 × 20/100 = 200/100 = 2

20% × 50 = 20 × 50/100 = 1000/100 = 10

50% × 40 = 50 × 40/100 = 2000/100 = 20

20% × 60 = 20 × 60/100 = 1200/100 = 12

30% × 60 = 30 × 60/100 = 1800/100 = 18

10% × 80 = 10 × 80/100 = 800/100 = 8

50% × 70 = 50 × 70/100 = 3500/100 = 35

60% × 20 = 60 × 20/100 = 1200/100 = 12

40% × 80 = 40 × 80/100 = 3200/100 = 32

30% × 80 = 30 × 80/100 = 2400/100 = 24

20% × 80 = 20 × 80/100 = 1600/100 = 16

40% × 50 = 40 × 50/100 = 2000/100 = 20

Espero que ajude
