To add or subtract these fractions, we first need to find a common denominator.

For 5 and 6/55, the common denominator is 55. So, we have:

5 = 5/1
6/55 = 6/55

Adding these fractions gives us:

5 + 6/55 = 5/1 + 6/55 = (555)/(155) + 6/55 = 275/55 + 6/55 = 281/55

Next, for 9/44 and 4, the common denominator is 44. So, we have:

9/44 = 9/44
4 = 4/1

Subtracting these fractions gives us:

9/44 - 4 = 9/44 - 4/1 = 9/44 - 176/44 = (9 - 176)/44 = -167/44

Lastly, for 7/22, there are no fractions to combine.

Therefore, the final result is:

5 + 6/55 = 281/55
9/44 - 4 = -167/44
7/22 = 7/22
