Solve the following arithmetic problems: 7200:90= 400 x 90= 800:20= 80 x 20 = 600: 20= 600 x 20= 800:20= 600 x 90= 350:50= 900 x 10= 800:10= 400x10=

Решение:

• \( 7200 : 90 = 80 \)
• \( 400 \times 90 = 36000 \)
• \( 800 : 20 = 40 \)
• \( 80 \times 20 = 1600 \)
• \( 600 : 20 = 30 \)
• \( 600 \times 20 = 12000 \)
• \( 800 : 20 = 40 \)
• \( 600 \times 90 = 54000 \)
• \( 350 : 50 = 7 \)
• \( 900 \times 10 = 9000 \)
• \( 800 : 10 = 80 \)
• \( 400 \times 10 = 4000 \)

Ответ: 80, 36000, 40, 1600, 30, 12000, 40, 54000, 7, 9000, 80, 4000.
