Answer 1

Ответ:

3/8+7/8=10/8=1 2/8

5/18+11/12= 10/36+33/36=43/36=1 7/36

2/11-5/11=11/11-5/11=6/11

8/9-5/9=3/9

3/5+2/5=5/5=1

8/17+1/17=9/17

1/4+1/6=3/12+2/12=5/12

5/8+1/8=6/8=3/4

7/9-1/9=6/9=2/3

2/14+3/21=1/7+1/7=2/7

Answer 2

Let's solve each of these equations step by step:

1. 3/8 + 7/8: (3/8) + (7/8) = (3 + 7)/8 = 10/8 = 5/4

2. 5/18 + 11/12: To add these fractions, you need to find a common denominator, which is 36. (5/18) * (2/2) = 10/36 (11/12) * (3/3) = 33/36 Now, you can add them: (10/36) + (33/36) = 43/36

3. 2/11 - 5/11: Since the denominators are the same, you can subtract the numerators directly: (2 - 5)/11 = -3/11

4. 8/9 - 5/9: Since the denominators are the same, you can subtract the numerators directly: (8 - 5)/9 = 3/9 To simplify further, you can divide both the numerator and denominator by their greatest common divisor, which is 3: (3/3) / (9/3) = 1/3

5. 3/5 + 2/5: Since the denominators are the same, you can add the numerators directly: (3 + 2)/5 = 5/5 = 1

6. 8/17 + 1/17: Since the denominators are the same, you can add the numerators directly: (8 + 1)/17 = 9/17

7. 1/4 + 1/6: To add these fractions, you need to find a common denominator, which is 12. (1/4) * (3/3) = 3/12 (1/6) * (2/2) = 2/12 Now, you can add them: (3/12) + (2/12) = 5/12

8. 5/8 + 1/8: Since the denominators are the same, you can add the numerators directly: (5 + 1)/8 = 6/8 To simplify further, you can divide both the numerator and denominator by their greatest common divisor, which is 2: (6/2) / (8/2) = 3/4

9. 7/9 - 1/9: Since the denominators are the same, you can subtract the numerators directly: (7 - 1)/9 = 6/9 To simplify further, you can divide both the numerator and denominator by their greatest common divisor, which is 3: (6/3) / (9/3) = 2/3

10. 2/14 + 3/21: To add these fractions, you need to find a common denominator, which is 42. (2/14) * (3/3) = 6/42 (3/21) * (2/2) = 6/42 Now, you can add them: (6/42) + (6/42) = 12/42

You've successfully solved each of these equations.
