Answer 2

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

1. 5 7/8 + 6 3/10: To add mixed numbers, first add the whole numbers and then add the fractions separately. 5 + 6 = 11 (whole numbers) 7/8 + 3/10 = (35/40 + 24/40) = 59/40

   Now, we can combine the whole numbers and fractions: 11 + 59/40 = 11 59/40

2. 10 3/75 + 14 3/35 + 2 1/7: Again, add the whole numbers and fractions separately: 10 + 14 + 2 = 26 (whole numbers) 3/75 + 3/35 + 1/7 = (4/100 + 12/100 + 14/100) = 30/100 = 3/10

   Combine the whole numbers and fractions: 26 + 3/10 = 26 3/10

3. 3.45 + 2 4/9: To add a decimal and a mixed number, convert the mixed number to a decimal and then add: 2 4/9 = 2 + 4/9 = 2.4444... (repeating)

   Now, add the decimals: 3.45 + 2.4444... = 5.8944...

4. 7 7/8 - 3.18: Subtract the whole numbers and fractions separately: 7 - 3 = 4 (whole numbers) 7/8 - 0.18 = 7/8 - 18/100 = (87/100 - 18/100) = 69/100

   Combine the whole numbers and fractions: 4 69/100 = 4.69

5. 19.75 - 19 3/16: To subtract a mixed number from a decimal, convert the mixed number to a decimal and then subtract: 19 3/16 = 19 + 3/16 = 19.1875

   Now, subtract the decimals: 19.75 - 19.1875 = 0.5625

6. 6 4/9 - 3 7/6: Subtract the whole numbers and fractions separately: 6 - 3 = 3 (whole numbers) 4/9 - 7/6 = (8/18 - 21/18) = -13/18

   Combine the whole numbers and fractions: 3 - 13/18 = 3 - 0.7222... = 2.2777... (repeating)

So, the results are:

1. 5 7/8 + 6 3/10 = 11 59/40
2. 10 3/75 + 14 3/35 + 2 1/7 = 26 3/10
3. 3.45 + 2 4/9 = 5.8944...
4. 7 7/8 - 3.18 = 4.69
5. 19.75 - 19 3/16 = 0.5625
6. 6 4/9 - 3 7/6 = 2.2777...
