- Поставьте знаки арифметических действий: 1. 20...4...2 =40                           2. 30...6...3 =15                                 20...4...2 =26                               30...6...3 = 27                                    20...4...2 =18                               30...6...3 = 39                                

Answer 1

1) 20*4/2
2)30/(6/3)
3) 20+4+2
4) (30-6)+3
5)(20-4)+2
6) 30+6+3

Answer 2

1. 20*4:2 2.30:6*3 3. 20+4+2 4. 30-6+3 5. 20-4+2 6. 30+6+3

Answer 3

1. 20 × 4 ÷ 2 = 40
2. 30 ÷ 6 - 3 = 15
3. 20 + 4 - 2 = 22
4. 30 - 6 ÷ 3 = 28
5. 20 - 4 ÷ 2 = 18
6. 30 + 6 × 3 = 48
