Answer 1

Respuesta:

 90              160

  9               600

120             800

300            200

900            100

  0              280

400            750

1200           700

Explicación paso a paso:

5 × 8 = 40 + 4 = 44 × 2 = 88 + 2 = 90 × 1 = 90

2 × 9 = 18 + 2 = 20 × 10 = 30 + 50 = 80 × 2 = 160

10 × 7 = 70 + 15 = 85 × 0 = 0 + 1 = 1 × 9 = 9

7 × 3 = 21 + 9 = 30 × 3 = 90 + 10 = 100 × 6 = 600

4 × 5 = 20 + 8 = 28 × 1 = 28 + 2 = 30 × 4 = 120

20 × 4 = 80 + 20 = 100 × 3 = 300 + 100 = 400 × 2 = 800

7 × 2 = 14 + 6 = 20 × 5 = 100 + 50 = 150 × 2 = 300

8 × 9 = 72 + 8 = 80 × 1 = 80 + 20 = 100 × 2 = 200

25 × 4 = 100 + 20 = 120 × 2 = 240 + 60 = 300 × 3 = 900

4 × 9 = 36 + 4 = 40 × 2 = 80 + 20 = 100 × 1 = 100

5 × 9 = 45 + 7 = 52 × 2 = 104 + 6 = 110 × 0 = 0

2 × 3 = 6 + 15 = 21 × 3 = 63 + 7 = 70 × 4 = 280

10 × 4 = 40 + 10 = 50 × 3 = 150 + 50 = 200 × 2 = 400

8 × 12 = 96 + 4 = 100 × 7 = 700 + 50 = 750 × 1 = 750

9 × 8 = 72 + 8 = 80 × 4 = 320 + 80 = 400 × 3 = 1200

9 × 12 = 108 + 2 = 110 × 3 = 330 + 20 = 350 × 2 = 700
