Calculation of Arithmetic Expressions

To solve the given arithmetic expressions, let's break them down step by step:

1. 4 2/9 + 2 целых 3/5 6: - To add mixed numbers, we need to convert them into improper fractions. - 2 целых 3/5 can be written as 2 + 3/5 = 10/5 + 3/5 = 13/5. - Now, we can add 4 2/9 and 13/5. - To add fractions, we need a common denominator. The least common multiple (LCM) of 9 and 5 is 45. - Converting 4 2/9 to an improper fraction: 4 * 9 + 2 = 38/9. - Converting 13/5 to an improper fraction: 13/5 = 39/15. - Adding the fractions: 38/9 + 39/15 = (38 * 5 + 39 * 9) / (9 * 15) = 285/45 = 6 5/9.

2. 5/7 + 3 целых 1/7: - To add mixed numbers, we need to convert them into improper fractions. - 3 целых 1/7 can be written as 3 + 1/7 = 21/7 + 1/7 = 22/7. - Now, we can add 5/7 and 22/7. - To add fractions, we need a common denominator. The least common multiple (LCM) of 7 is 7. - Adding the fractions: 5/7 + 22/7 = (5 + 22) / 7 = 27/7 = 3 6/7.

3. 9 целых 5/8 - 2: - To subtract a whole number from a mixed number, we need to convert them into improper fractions. - 9 целых 5/8 can be written as 9 + 5/8 = 72/8 + 5/8 = 77/8. - Now, we can subtract 2 from 77/8. - Subtracting the fractions: 77/8 - 2 = (77 - 2 * 8) / 8 = (77 - 16) / 8 = 61/8 = 7 5/8.

4. 5 целых 7/10 - 4/10: - To subtract fractions, we need a common denominator. The least common multiple (LCM) of 10 is 10. - 5 целых 7/10 can be written as 5 + 7/10 = 50/10 + 7/10 = 57/10. - Subtracting the fractions: 57/10 - 4/10 = (57 - 4) / 10 = 53/10 = 5 3/10.

5. 6 целых 2/3 - 2/3: - To subtract fractions, we need a common denominator. The least common multiple (LCM) of 3 is 3. - 6 целых 2/3 can be written as 6 + 2/3 = 18/3 + 2/3 = 20/3. - Subtracting the fractions: 20/3 - 2/3 = (20 - 2) / 3 = 18/3 = 6.

6. 1 целая 3/11 + 3 целых 6/11: - To add mixed numbers, we need to convert them into improper fractions. - 1 целая 3/11 can be written as 1 + 3/11 = 11/11 + 3/11 = 14/11. - 3 целых 6/11 can be written as 3 + 6/11 = 33/11 + 6/11 = 39/11. - Now, we can add 14/11 and 39/11. - Adding the fractions: 14/11 + 39/11 = (14 + 39) / 11 = 53/11 = 4 9/11.

7. 7 целых 5/13 - 2 целых 4/13: - To subtract mixed numbers, we need to convert them into improper fractions. - 7 целых 5/13 can be written as 7 + 5/13 = 91/13 + 5/13 = 96/13. - 2 целых 4/13 can be written as 2 + 4/13 = 26/13 + 4/13 = 30/13. - Now, we can subtract 30/13 from 96/13. - Subtracting the fractions: 96/13 - 30/13 = (96 - 30) / 13 = 66/13 = 5 1/13.

8. 1 - 5/12: - To subtract a fraction from a whole number, we need to convert the whole number into a fraction. - 1 can be written as 12/12. - Now, we can subtract 5/12 from 12/12. - Subtracting the fractions: 12/12 - 5/12 = (12 - 5) / 12 = 7/12.

Therefore, the solutions to the given arithmetic expressions are: 1. 4 2/9 + 2 целых 3/5 6 = 6 5/9 2. 5/7 + 3 целых 1/7 = 3 6/7 3. 9 целых 5/8 - 2 = 7 5/8 4. 5 целых 7/10 - 4/10 = 5 3/10 5. 6 целых 2/3 - 2/3 = 6 6. 1 целая 3/11 + 3 целых 6/11 = 4 9/11 7. 7 целых 5/13 - 2 целых 4/13 = 5 1/13 8. 1 - 5/12 = 7/12
