Adding Decimals

In the following problems, add the numbers using tidy whole number and compensating to solve the problems below.  Then, CREATE a problem of your own and explain how you solved it step by step on your BLOG.
Example:
? + 3.98 = 7.04
3.98 + ?  = 7.04
3.98 + 0.02 =4.0
        4 + 3 =7
   7 +.0.04 = 7.04
So ? = 3.06


1. 4.64 + 5.36  = 10.87 4. 7.33 + 26.21 = 34.54
 



2. 8.23 + 4.43 = 13.56         5. 22.38 + 43.26 = 65.64




3. 3.39 + 11.14 = 14.53 6. 14.10 + 84.74 = 98.84

       5.15.15+ 4.98 = 20.20
           +0.2
15.15 + 5.05 = 20.20
