Let's solve the given addition step by step.

The initial expression is:

\[ 12.1 + 9.4 + 5.6 \]

1. First, add \( 12.1 \) and \( 9.4 \):

\[ 12.1 + 9.4 = 21.5 \]

2. Then, add \( 21.5 \) and \( 5.6 \):

\[ 21.5 + 5.6 = 27.1 \]

Therefore, the sum of \( 12.1 + 9.4 + 5.6 \) is \( 27.1 \).

If we consider your intermediate steps:

\[ 12.1 + 9.4 + 15.0 \]

First, add \( 12.1 \) and \( 9.4 \):

\[ 12.1 + 9.4 = 21.5 \]

Then add \( 21.5 \) to \( 15.0 \):

\[ 21.5 + 15.0 = 36.5 \]

Thus, the sum would be \( 36.5 \).

It seems there might be a misunderstanding in the intermediate steps provided. The final correct sum of the original problem is \( 27.1 \).
