Answer 1

84:12=7

42*2-42=42

80:(4+76)=1

56:18=3целых 1/9

4*15+15=75

96-64:4=80

(96-64):4=8

78:26=3

6*13-13=65

56:8*7=49

63:9*5=35

70:10=7

Answer 2

Let's solve the given equations step-by-step:

1. 84:12 = ? To find the result of this division, simply divide 84 by 12: 84 ÷ 12 = 7

So, 84:12 = 7

2. 42×2 - 42 = ? First, multiply 42 by 2, and then subtract 42 from the result: 42 × 2 = 84 84 - 42 = 42

So, 42×2 - 42 = 42

3. 80:(4+76) = ? First, calculate the value inside the parentheses, which is (4 + 76) = 80 Now, divide 80 by 80: 80 ÷ 80 = 1

So, 80:(4+76) = 1

4. 56:18 = ? To find the result of this division, simply divide 56 by 18: 56 ÷ 18 = 3.1111... (recurring decimal, rounded to 4 decimal places)

So, 56:18 ≈ 3.1111

5. 4×15 + 15 = ? First, multiply 4 by 15, and then add 15 to the result: 4 × 15 = 60 60 + 15 = 75

So, 4×15 + 15 = 75

6. 96-64:4 = ? First, divide 64 by 4: 64 ÷ 4 = 16 Now, subtract 16 from 96: 96 - 16 = 80

So, 96-64:4 = 80

7. (96-64):4 = ? First, subtract 64 from 96: 96 - 64 = 32 Now, divide 32 by 4: 32 ÷ 4 = 8

So, (96-64):4 = 8

8. 78:26 = ? To find the result of this division, simply divide 78 by 26: 78 ÷ 26 = 3

So, 78:26 = 3

9. 6×13-13 = ? First, multiply 6 by 13, and then subtract 13 from the result: 6 × 13 = 78 78 - 13 = 65

So, 6×13-13 = 65

10. 56:8×7 = ? First, divide 56 by 8: 56 ÷ 8 = 7 Now, multiply 7 by 7: 7 × 7 = 49

So, 56:8×7 = 49

11. 63:9×5 = ? First, divide 63 by 9: 63 ÷ 9 = 7 Now, multiply 7 by 5: 7 × 5 = 35

So, 63:9×5 = 35

12. 70:10 = ? To find the result of this division, simply divide 70 by 10: 70 ÷ 10 = 7

So, 70:10 = 7

Therefore, the answers to the given equations are as follows:

1. 84:12 = 7
2. 42×2 - 42 = 42
3. 80:(4+76) = 1
4. 56:18 ≈ 3.1111
5. 4×15 + 15 = 75
6. 96-64:4 = 80
7. (96-64):4 = 8
8. 78:26 = 3
9. 6×13-13 = 65
10. 56:8×7 = 49
11. 63:9×5 = 35
12. 70:10 = 7
