Составь и реши 3 собственных примера на умножение круглых чисел

Пример 1:

200 ⋅ 30 = 2 ⋅ 3 ⋅ 100 ⋅ 10 = 6 ⋅ 1000 = 6000

Пример 2:

5000 ⋅ 400 = 5 ⋅ 4 ⋅ 1000 ⋅ 100 = 20 ⋅ 100000 = 200000

Пример 3:

120 ⋅ 6000 = 12 ⋅ 6 ⋅ 10 ⋅ 1000 = 72 ⋅ 10000 = 720000

Ответ: 200 ⋅ 30 = 6000; 5000 ⋅ 400 = 200000; 120 ⋅ 6000 = 720000
