Answer 2

To solve this addition and subtraction of mixed numbers, follow these steps:

Step 1: Convert all mixed numbers to improper fractions. Step 2: Perform the addition and subtraction operations. Step 3: If the result is an improper fraction, convert it back to a mixed number (if desired).

Let's proceed with the calculations:

Step 1: Convert mixed numbers to improper fractions 5 2/3 = (5 * 3 + 2) / 3 = 17 / 3 11 7/12 = (11 * 12 + 7) / 12 = 139 / 12 4 3/4 = (4 * 4 + 3) / 4 = 19 / 4

Step 2: Perform the addition and subtraction 17 / 3 + 139 / 12 - 19 / 4

Step 3: Find a common denominator for the fractions (which is 12), and adjust each fraction accordingly: (17 / 3) * (4 / 4) = 68 / 12 (139 / 12) * (1 / 1) = 139 / 12 (19 / 4) * (3 / 3) = 57 / 12

Now, the expression becomes: 68 / 12 + 139 / 12 - 57 / 12

Step 4: Combine the fractions: (68 + 139 - 57) / 12 = 150 / 12

Step 5: Reduce the fraction (if possible): 150 / 12 = 12 and 6/12 or 12 and 1/2

So, the final result is 12 1/2.
