Step-by-Step Solution

To solve this problem, let's add the decimal numbers $1.6$ and $0.5$ as follows:

Step 1: Write the numbers $1.6$ and $0.5$ in a column, ensuring that the decimal points are aligned:
$\begin{array}{c} 1.6 \\ +0.5 \\ \hline \end{array}$
Step 2: Begin with the rightmost digits (tenths place). Add $6$ (from $1.6$ ) and $5$ (from $0.5$ ):
$6 + 5 = 11$ . Write down the $1$ in the tenths place and carry over the other $1$ to the units place.
Step 3: Move to the units place. Add $1$ (carried over) to $1$ (from $1.6$ ) and $0$ (from $0.5$ ):
$1 + 1 + 0 = 2$ .
Step 4: Combine the sums from Steps 2 and 3 to get the final result.

Thus, the sum of $1.6$ and $0.5$ is $2.1$ .

The correct answer is $2.1$ .
