Answer 2

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

1. Calculate the absolute values:

   |5/6| = 5/6 |-7/9| = 7/9 |-14| = 14 |-4| = 4 |-63| = 63 |-0.7| = 0.7

2. Perform the operations:

   5/6 + 7/9 - 14 * 4 - 63 / 0.7

   5/6 + 7/9 - 56 - 90

3. Find a common denominator:

   Common denominator for 6 and 9 is 18.

   Multiply the fractions by the appropriate factors:

   (5 * 3)/(6 * 3) + (7 * 2)/(9 * 2) - 56 - 90

   15/18 + 14/18 - 56 - 90

4. Combine the fractions:

   29/18 - 56 - 90

5. Convert 29/18 to a mixed number:

   1 11/18

6. Subtract the remaining numbers:

   1 11/18 - 56 - 90

   -144 7/18

So, the result is approximately -144.39.
