Ответ: 28 + 42 : 7 – 6 = 28; 96 – 72 : 9 + 15 = 103; 32 + 56 : 8 – 7 = 32; 100 – 7 \(\cdot\) 8 = 44; 90 – 8 \(\cdot\) 8 = 26; 80 – 9 \(\cdot\) 8 = 8; 74 : 9 = 8 (ост. 2); 65 : 9 = 7 (ост. 2); 85 : 9 = 9 (ост. 4)

Выполним действия:

28 + 42 : 7 – 6 = 28 + 6 - 6 = 34 - 6 = 28

96 – 72 : 9 + 15 = 96 - 8 + 15 = 88 + 15 = 103

32 + 56 : 8 – 7 = 32 + 7 - 7 = 39 - 7 = 32

100 – 7 \(\cdot\) 8 = 100 - 56 = 44

90 – 8 \(\cdot\) 8 = 90 - 64 = 26

80 – 9 \(\cdot\) 8 = 80 - 72 = 8

74 : 9 = 8 (ост. 2)

65 : 9 = 7 (ост. 2)

85 : 9 = 9 (ост. 4)

Ответ: 28 + 42 : 7 – 6 = 28; 96 – 72 : 9 + 15 = 103; 32 + 56 : 8 – 7 = 32; 100 – 7 \(\cdot\) 8 = 44; 90 – 8 \(\cdot\) 8 = 26; 80 – 9 \(\cdot\) 8 = 8; 74 : 9 = 8 (ост. 2); 65 : 9 = 7 (ост. 2); 85 : 9 = 9 (ост. 4)
