Let's go through the process of adding the given decimals step by step.

1. First Set of Decimals:
- Adding 1.56 and 5.09:
[tex]\[ 1.56 + 5.09 = 6.65 \][/tex]
- Adding 8.77 and 5.34:
[tex]\[ 8.77 + 5.34 = 14.11 \][/tex]

2. Second Set of Decimals:
- Adding 9.15 and 4.53:
[tex]\[ 9.15 + 4.53 = 13.68 \][/tex]
- Adding 8.48 and 5.17:
[tex]\[ 8.48 + 5.17 = 13.65 \][/tex]

3. Third Set of Decimals:
- Adding 62.454 and 36.748:
[tex]\[ 62.454 + 36.748 = 99.202 \][/tex]
- Adding 81.282 and 52.810:
[tex]\[ 81.282 + 52.810 = 134.092 \quad (\text{slightly rounded as } 134.09199999999998) \][/tex]

4. Fourth Set of Decimals:
- Adding 12.982 and 15.484:
[tex]\[ 12.982 + 15.484 = 28.466 \][/tex]
- Adding 62.595 and 54.656:
[tex]\[ 62.595 + 54.656 = 117.251 \][/tex]

So, the results are:
- For the first set: [tex]\(6.65\)[/tex] and [tex]\(14.11\)[/tex]
- For the second set: [tex]\(13.68\)[/tex] and [tex]\(13.65\)[/tex]
- For the third set: [tex]\(99.202\)[/tex] and [tex]\(134.092\)[/tex]
- For the fourth set: [tex]\(28.466\)[/tex] and [tex]\(117.251\)[/tex]

Hence, when adding the given decimals, we obtain:
[tex]\[ (6.65, 14.11, 13.68, 13.65, 99.202, 134.092, 28.466, 117.251) \][/tex]
