Answer 1

1)45.294 2)-6.097 3)-12.847

Answer 2

Let's calculate the given expressions step by step:

1. 18,349 + 26,945 = 45,294
2. 3,647 - 8,550 = -4,903
3. ? - 19.71 + 6.853 = ? - 12.857 (The missing value can be determined by further context or calculation.)
4. ? - 6.42(8) + 17.19 = ? + 10.77 (The missing value can be determined by further context or calculation.)
5. ? - 5.009 - 8.(45) = ? - 13.459 (The missing value can be determined by further context or calculation.)
6. 12,345.6789 + 98,765.4321 = 111,111.111 (The sum of the two numbers is 111,111.111.)
7. 4 1/7 + 2.72 = 6.987 (The sum of the two numbers is 6.987.)
8. 15.94 - 15 9/11 = 0.03 (The difference between the two numbers is 0.03.)
9. -2 2/3 + 3.(7) = 1.(0) (The sum of the two numbers is 1.(0).)
10. -8.0(8) - 5 7/13 = -13.(1) (The difference between the two numbers is -13.(1).)
11. 7/8 * 2/5 = 7/20 (The product of the two fractions is 7/20.)
12. 36/44 * 11/12 = 3/4 (The product of the two fractions is 3/4.)
13. 3 12/16 * 4/10 = 2 7/20 (The product of the two mixed numbers is 2 7/20.)
14. 2 1/4 * 1 23/45 = 2 31/180 (The product of the two mixed numbers is 2 31/180.)

Note: Please clarify the missing values (?) in expressions 3, 4, and 5 if you need the exact results.
