2. \begin{array}{l} 37.2 \\ 103. \\ \( +\quad 8.52 \\ \)\hline\end{array}

To add the numbers \(37.2\), \(103.0\), and \(8.52\), we can align them by their decimal points: \[ \begin{array}{r} 37.20 \\ +103.00 \\ + 8.52 \\ \hline \end{array} \] Now, let's add them step by step: 1. Start from the rightmost column (hundredths): - \(0 + 0 + 2 = 2\) 2. Move to the tenths column: - \(2 + 0 + 5 = 7\) 3. Move to the units column: - \(7 + 3 + 8 = 18\) (write down 8 and carry over 1) 4. Move to the tens column: - \(1 + 1 + 0 + 1 = 3\) 5. Finally, the hundreds column: - \(1 + 0 = 1\) Putting it all together, we have: \[ \begin{array}{r} 37.20 \\ +103.00 \\ + 8.52 \\ \hline 148.72 \\ \end{array} \] Thus, the sum of \(37.2\), \(103.0\), and \(8.52\) is \(148.72\).
