Nazorat ishlarini o‘tkazish yuzasidan tavsiyalar

JAVOBLAR:

I variant

1. Ko`paytirishni bajaring: 42 * 3= 126 64 * 4= 256 18 * 3= 54 23 * 4= 92

2. Bo‘lishni bajaring: 44 : 22= 2 84 : 28= 3 91 : 13= 7

3. Amallarni bajaring: 72 : 6 + 18= 30 13 * 5 – 48 : 12= 61

4. 48-(6*7)=48-42= 6

5. (27-6):3=21:3= 7

II variant

1. Ko`paytirishni bajaring: 36 * 3= 108 72 * 6= 432 14 * 4= 56 13 * 7= 91

2. Bo‘lishni bajaring: 66 : 33= 2 78 : 26= 3 96 : 12= 8

3. Amallarni bajaring 84 : 7 + 48=60 24 * 4 – 32 : 16= 94

4. 8*9+16=72+16= 88

5. (54-12)+54=42+54= 96
