Solve the following arithmetic problems: 200 x 20= 1000:20= 300x20= 1600: 20= 400x20= 900:30= 7200:80= 600x10= 100x80= 1500: 5=

Решение:

• \( 200 \times 20 = 4000 \)
• \( 1000 : 20 = 50 \)
• \( 300 \times 20 = 6000 \)
• \( 1600 : 20 = 80 \)
• \( 400 \times 20 = 8000 \)
• \( 900 : 30 = 30 \)
• \( 7200 : 80 = 90 \)
• \( 600 \times 10 = 6000 \)
• \( 100 \times 80 = 8000 \)
• \( 1500 : 5 = 300 \)

Ответ: 4000, 50, 6000, 80, 8000, 30, 90, 6000, 8000, 300.
