(63  2/3  + 3  1/8  )  -  (13  -10  5/9) =
= ( 63 16/24  +  3   3/24 )  -   2  4/9  =
= 66  19/24    -  2  4/9=
= 66  57/ 72  -  2   32/72 =
= 64  25/72

Answer 3

To calculate the expression (63 2/3 + 3 1/8) - (13 - 10 5/9), you can follow these steps:

1. First, simplify the fractions and mixed numbers within parentheses:

   • 63 2/3 = 63 + 2/3
   • 3 1/8 = 3 + 1/8
   • 10 5/9 = 10 + 5/9

2. Now, add and subtract the numbers separately:

   • (63 + 2/3) + (3 + 1/8) - (13 - 10 - 5/9)

3. Calculate each part:

   • (63 + 2/3) = 63 + 2/3 = 63 + 2/3
   • (3 + 1/8) = 3 + 1/8 = 3 + 1/8
   • (13 - 10 - 5/9) = 13 - 10 - 5/9 = 3 - 5/9

4. Now, simplify the expression:

   • (63 + 2/3) + (3 + 1/8) - (3 - 5/9)

5. Continue to calculate:

   • 63 + 2/3 = 63 2/3
   • 3 + 1/8 = 3 1/8
   • 3 - 5/9 = 2 4/9

6. Now, you have:

   • (63 2/3) + (3 1/8) - (2 4/9)

7. Finally, add and subtract the mixed numbers:

   • (63 + 3 - 2) + (2/3 + 1/8 - 4/9)

8. Calculate each part:

   • 63 + 3 - 2 = 64

   • (2/3 + 1/8 - 4/9) is a bit more complex. To add these fractions, you'll need a common denominator. The least common multiple of 3, 8, and 9 is 72. Rewrite each fraction with a denominator of 72:

     • (2/3 * 24/24 + 1/8 * 9/9 - 4/9 * 8/8) = (48/72 + 9/72 - 32/72)

9. Now, add the fractions:

   • (48/72 + 9/72 - 32/72) = 25/72

10. So the final result is:

• 64 + 25/72

This is the answer to the expression: (63 2/3 + 3 1/8) - (13 - 10 5/9).
