Answer 2

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

1. 6/57 + 4 = To add these, we need to find a common denominator for 57 and 1 (since 4 can be written as 4/1): Common denominator = 57 Now, convert 4 to a fraction with the denominator 57: 4 = 4 * 57/57 = 228/57 Now add: 6/57 + 228/57 = (6 + 228)/57 = 234/57 Reduce the fraction if possible: 234/57 = 78/19

Answer: 6/57 + 4 = 78/19

2. 6 4/9 + 5 2/9 = To add mixed fractions, we first add the whole numbers and then the fractional parts: 6 + 5 = 11 (whole numbers) 4/9 + 2/9 = 6/9 = 2/3 (fractions) Now add the whole numbers and fractions: 11 + 2/3 = 11 2/3

Answer: 6 4/9 + 5 2/9 = 11 2/3

3. 11 8/11 - 3 5/11 = To subtract mixed fractions, we first subtract the whole numbers and then the fractional parts: 11 - 3 = 8 (whole numbers) 8/11 - 5/11 = 3/11 (fractions) Now subtract the whole numbers and fractions: 8 - 3 = 5 and 3/11

Answer: 11 8/11 - 3 5/11 = 5 3/11

4. 8 7/18 + 7 5/18 - 4 11/18 = To add and subtract mixed fractions, follow the same steps as above: 8 + 7 - 4 = 11 (whole numbers) 7/18 + 5/18 - 11/18 = 1/18 (fractions) Now add the whole numbers and fractions: 11 + 1/18 = 11 1/18

Answer: 8 7/18 + 7 5/18 - 4 11/18 = 11 1/18

5. 13 6/10 - 5 3/10 + 16 1/10 = To add and subtract mixed fractions, follow the same steps as above: 13 - 5 + 16 = 24 (whole numbers) 6/10 - 3/10 + 1/10 = 4/10 = 2/5 (fractions) Now add the whole numbers and fractions: 24 + 2/5 = 24 2/5

Answer: 13 6/10 - 5 3/10 + 16 1/10 = 24 2/5

6. 4 13/17 + 5 4/17 = To add mixed fractions, follow the same steps as above: 4 + 5 = 9 (whole numbers) 13/17 + 4/17 = 17/17 = 1 (fractions) Now add the whole numbers and fractions: 9 + 1 = 10

Answer: 4 13/17 + 5 4/17 = 10

7. 3 8/11 + 2 6/11 = To add mixed fractions, follow the same steps as above: 3 + 2 = 5 (whole numbers) 8/11 + 6/11 = 14/11 (fractions) Since the fraction 14/11 is improper, we can simplify it to a mixed fraction: 14/11 = 1 3/11 Now add the whole numbers and fractions: 5 + 1 3/11 = 6 3/11

Answer: 3 8/11 + 2 6/11 = 6 3/11

8. 1 - 16/21 = To subtract a fraction, we need to find a common denominator for 1 and 21 (since 16/21 already has the denominator 21): Common denominator = 21 Now, convert 1 to a fraction with the denominator 21: 1 = 1 * 21/21 = 21/21 Now subtract: 21/21 - 16/21 = (21 - 16)/21 = 5/21

Answer: 1 - 16/21 = 5/21

9. 5 - 2 3/8 = To subtract mixed fractions, follow the same steps as above: 5 - 2 = 3 (whole numbers) We need to find a common denominator for 8 and 1 (since 2 can be written as 16/8): Common denominator = 8 Now, convert 2 to a fraction with the denominator 8: 2 = 16/8 Now subtract: 3 - 16/8 = 3 - 2 = 1

Answer: 5 - 2 3/8 = 1

10. 8 4/9 - 3 7/9 = To subtract mixed fractions, follow the same steps as above: 8 - 3 = 5 (whole numbers) 4/9 - 7/9 = -3/9 = -1/3 (fractions) Now subtract the whole numbers and fractions: 5 - 1/3 = 4 2/3

Answer: 8 4/9 - 3 7/9 = 4 2/3

11. 12 19/44 - 6 37/44 = To subtract mixed fractions, follow the same steps as above: 12 - 6 = 6 (whole numbers) 19/44 - 37/44 = -18/44 = -9/22 (fractions) Now subtract the whole numbers and fractions: 6 - 9/22 = 5 13/22

Answer: 12 19/44 - 6 37/44 = 5 13/22
