1. Вычисли: 105:7 = 66:6= 28.4 = 305.3 = 100:50 = 960 : 4 = 53:7 = 243: 8 = 405:10 =

Решение:

1. 105 : 7 = 15

   66 : 6 = 11

   28 \(\times\) 4 = 112

2. 305 \(\times\) 3 = 915

   100 : 50 = 2

   960 : 4 = 240

3. 53 : 7 = 7 (ост. 4)

   243 : 8 = 30 (ост. 3)

   405 : 10 = 40 (ост. 5)

Ответ: 15, 11, 112, 915, 2, 240, 7 (ост. 4), 30 (ост. 3), 40 (ост. 5).
