Answer 1

7 8/19 +2 3/19 - 8 11/19+3 5/19 =4 4/19

7 8/19+2 3/19=9 10/19

9 10/19-8 11/19=18/19

18/19+3 5/19=4 4/19

Answer 2

Let's simplify each fraction first:

• 7 8/19 can be converted to an improper fraction: (7 × 19 + 8) / 19 = 141/19
• 2 3/19 can be converted to an improper fraction: (2 × 19 + 3) / 19 = 41/19
• 8 11/19 can be converted to an improper fraction: (8 × 19 + 11) / 19 = 163/19
• 3 5/19 can be converted to an improper fraction: (3 × 19 + 5) / 19 = 62/19

So the expression becomes:

(141/19 + 41/19) - (163/19 - 62/19)

Now we can add and subtract the fractions:

= 182/19 - 101/19

= 81/19

Therefore, (7 8/19 +2 3/19) - (8 11/19-3 5/19) = 81/19.
