To estimate the sum of the numbers \(1.8\), \(2.345\), \(0.65\), and \(13.56\), we can round each number to the nearest whole number:
- \(1.8\) rounds to \(2\)
- \(2.345\) rounds to \(2\)
- \(0.65\) rounds to \(1\)
- \(13.56\) rounds to \(14\)
Now, we add the rounded numbers together:
\[
2 + 2 + 1 + 14 = 19
\]
Therefore, the estimated sum to the nearest whole number is \(19\).
- \(1.8\) rounds to \(2\)
- \(2.345\) rounds to \(2\)
- \(0.65\) rounds to \(1\)
- \(13.56\) rounds to \(14\)
Now, we add the rounded numbers together:
\[
2 + 2 + 1 + 14 = 19
\]
Therefore, the estimated sum to the nearest whole number is \(19\).
