Ответ:

Пошаговое объяснение:

6 + 5/13 = 6. 5/13

6/57 + 4 = 4. 6/57

6. 4/9 + 5/9 = 6. 9/9 = 7

11. 8/11 - 3. 5/11 = 8. 3/11

87/18 + 7 - 5/18 - 4. 11/18 = 4. 15/18 + 7 - 5/18 - 4. 11/18 = 11. 15/18 - 5/18 - 4. 11/18 = 11. 10/18 - 4. 11/18 = 10. 28/18 - 4. 11/18 = 6. 17/18

13. 6/10 - 5. 3/10 + 16. 1/10 = 8. 3/10 + 16. 1/10 = 24. 4/10 = 24. 2/5

Answer 3

Let's solve each of these arithmetic expressions step by step:

1. 6 + 5/13: 6 + 5/13 = 78/13 + 5/13 = (78 + 5)/13 = 83/13

2. 6/57 + 4: 6/57 + 4 = 2/19 + 4 = (2 + 76)/19 = 78/19

3. 6 4/9 + 5/9: To add these fractions, we need a common denominator, which is 9: 6 4/9 + 5/9 = 6 + 4/9 + 5/9 = 6 + (4 + 5)/9 = 6 + 9/9 = 7

4. 11 8/11 - 3 5/11: To subtract these mixed numbers, we first subtract the whole numbers and then the fractions: (11 - 3) + (8/11 - 5/11) = 8 + (3/11) = 8 3/11

5. 87/18 + 7 - 5/18 - 4 11/18: First, add the fractions together, then subtract the whole number and fraction from the result: (87/18 - 5/18) + 7 - 4 11/18 = 82/18 + 7 - 4 11/18 To make the fractions easier to work with, simplify 82/18: 82/18 = 41/9 Now, we have: (41/9) + 7 - 4 11/18 To subtract 4 11/18, convert it to an improper fraction: 4 11/18 = (4 * 18 + 11)/18 = 83/18 Now, the expression becomes: (41/9) + 7 - (83/18) To add and subtract fractions, we need a common denominator, which is 18: [(41 * 2)/18] + [(7 * 18)/18] - (83/18) = (82/18) + (126/18) - (83/18) Now, subtract and add the fractions: (82 + 126 - 83)/18 = 125/18

6. 13 6/10 - 5 3/10 + 16 1/10: First, add the whole numbers: (13 + 16) = 29 Next, add and subtract the fractions: (6/10 - 3/10 + 1/10) = (4/10) = (2/5) Now, combine the whole number and fraction: 29 + 2/5 = 29 2/5

So, the results are:

1. 83/13
2. 78/19
3. 7
4. 8 3/11
5. 125/18
6. 29 2/5
