Answer 2

Let's break down the expression step by step:

1. (19 13/7 - 3 13/17): First, we need to evaluate the expression inside the parentheses.

   • 19 13/7: This is a mixed number (whole number and fraction). It's equivalent to (19 * 7) + 13 = 140 + 13 = 153.
   • 3 13/17: This is another mixed number. It's equivalent to (3 * 17) + 13 = 51 + 13 = 64.

   So, the expression inside the parentheses becomes: 153 - 64 = 89.

2. (5 3/5 - 2 4/5): Now, let's evaluate the second expression in the parentheses.

   • 5 3/5: This is equivalent to (5 * 5) + 3 = 25 + 3 = 28.
   • 2 4/5: This is equivalent to (2 * 5) + 4 = 10 + 4 = 14.

   The expression inside the second set of parentheses becomes: 28 - 14 = 14.

3. (89) + (14): Now, we have the results of both sets of parentheses. Adding them together, we get 89 + 14 = 103.

4. (103) : 7: Finally, we divide 103 by 7. This gives us approximately 14.71 (rounded to two decimal places).

So, the overall expression evaluates to approximately 14.71.
