Answer 2

Let's break down the calculations step by step:

1. 21/30 + 3/30 - 8/30:

   • First, add 21/30 and 3/30: 21/30 + 3/30 = 24/30
   • Then, subtract 8/30 from the result: 24/30 - 8/30 = 16/30

2. 61/200 - (35/200 - 19/200):

   • First, subtract 35/200 from 61/200: 61/200 - 35/200 = 26/200
   • Then, add 19/200 to the result: 26/200 + 19/200 = 45/200

3. 21/65 - 16/65 + 13/65:

   • First, add 21/65 and 13/65: 21/65 + 13/65 = 34/65
   • Then, subtract 16/65 from the result: 34/65 - 16/65 = 18/65

4. 21/30 - (1/30 + 9/30):

   • First, add 1/30 and 9/30: 1/30 + 9/30 = 10/30
   • Then, subtract 10/30 from 21/30: 21/30 - 10/30 = 11/30

5. 17/19 - (5/19 + 2/19):

   • First, add 5/19 and 2/19: 5/19 + 2/19 = 7/19
   • Then, subtract 7/19 from 17/19: 17/19 - 7/19 = 10/19

6. 3/10 + 5/10 - 7/10:

   • First, add 3/10 and 5/10: 3/10 + 5/10 = 8/10
   • Then, subtract 7/10 from 8/10: 8/10 - 7/10 = 1/10

So, the final result is:

16/30 = 8/15 45/200 = 9/40 18/65 11/30 10/19 1/10
