Answer 3

To solve this expression, let's break it down step by step:

1. First, calculate the values inside the parentheses for each set:

   • For the first set of parentheses: 19 13/17 - 3 13/17 = 16 0/17
   • For the second set of parentheses: 5 3/5 - 2 4/5 = 2 4/5

2. Now, add the values inside the first set of parentheses to the values inside the second set of parentheses:

   • 16 0/17 + 2 4/5 = 18 4/5

3. Next, divide the result from step 2 by 7:

   • (18 4/5) / 7

4. To divide a mixed number by a whole number, convert the mixed number to an improper fraction and then perform the division:

   • Convert 18 4/5 to an improper fraction: (5 * 18 + 4) / 5 = (90 + 4) / 5 = 94/5

5. Now, divide 94/5 by 7:

   • (94/5) / 7 = (94/5) * (1/7) = (94/35)

So, the final result is 94/35, which is an improper fraction. If you want to convert it to a mixed number, you can do that as well:

• 94/35 as a mixed number:
  • Divide 94 by 35 to get the whole part: 94 ÷ 35 = 2 (whole part)
  • The remainder is 94 - (2 * 35) = 24
  • So, the mixed number is 2 24/35

Therefore, the final result is either 94/35 or 2 24/35, depending on whether you prefer an improper fraction or a mixed number.
