Answer 2

To solve this arithmetic expression, you can follow these steps:

1. Convert the mixed numbers (7 11/12 and 6 1/15) into improper fractions.
2. Perform the addition and subtraction.
3. Convert the result back to a mixed number if needed.

Let's do it step by step:

1. Convert mixed numbers to improper fractions: 7 11/12 = 7 + 11/12 = (7 * 12)/12 + 11/12 = 84/12 + 11/12 = 95/12 6 1/15 = 6 + 1/15 = (6 * 15)/15 + 1/15 = 90/15 + 1/15 = 91/15

2. Perform the addition and subtraction: 95/12 + 91/15 - 8.3

3. Find a common denominator for 12 and 15, which is 60. Adjust the fractions: (95/12) * (5/5) = 475/60 (91/15) * (4/4) = 364/60

Now the expression becomes: (475/60) + (364/60) - 8.3

4. Add and subtract the fractions: (475/60) + (364/60) = (475 + 364)/60 = 839/60

5. Subtract 8.3: (839/60) - 8.3

6. Convert the decimal 8.3 to a fraction with a denominator of 60: 8.3 = 8 + 0.3 = 8 + 3/10 = (8 * 10)/10 + 3/10 = 80/10 + 3/10 = 83/10

Now the expression becomes: (839/60) - (83/10)

7. Find a common denominator for 60 and 10, which is 60: (839/60) - (83/10) = (839/60) - (498/60)

8. Subtract the fractions: (839/60) - (498/60) = (839 - 498)/60 = 341/60

9. Simplify the fraction, if necessary. In this case, it's already simplified.

So, the final result is: 341/60
