Add Mixed Numbers Find the sum. \[ \begin{array}{r} 2 \frac{3}{10} \\ +\quad 1 \frac{5}{10} \\ \hline \end{array} \] \( 2 \frac{8}{10} \) \( 3 \frac{8}{20} \) \( 3 \frac{5}{10} \) \( 3 \frac{8}{10} \)

To add the mixed numbers \(2 \frac{3}{10}\) and \(1 \frac{5}{10}\), start by adding the whole numbers. \(2 + 1 = 3\). Next, combine the fractions: \(\frac{3}{10} + \frac{5}{10} = \frac{8}{10}\). So, the total is \(3 \frac{8}{10}\). Mixing fractions can sometimes be tricky, but remember to only add fractions with the same denominator. Also, if the sum of the fractions exceeds 1, convert that into a whole number instead of just stacking numbers!
