Evaluate. Check whether your answer is reasonable. \( \begin{array}{ll}\text { 13. } 1.7+5+4.3= & \text { 14. } 15.24+6.13-7=\end{array} \)

To evaluate the first expression, \(1.7 + 5 + 4.3\), we can simplify it step by step. First, adding \(1.7 + 5\) gives us \(6.7\). Next, adding \(6.7 + 4.3\) equals \(11\). Now, for the second expression, \(15.24 + 6.13 - 7\), let's perform it step by step as well. Starting with \(15.24 + 6.13\), which equals \(21.37\). Subtracting \(7\) from \(21.37\) results in \(14.37\). Now, checking if the answers are reasonable: \(1.7 + 5 + 4.3\) adds up to a little over \(10\), and \(15.24 + 6.13 - 7\) results in slightly more than \(14\), both of which seem quite reasonable in their respective contexts.
