Consider the following sum:

[tex]\[
\begin{array}{r}
67.09 \\
38.6 \\
+\quad 5.15 \\
\hline
\end{array}
\][/tex]

Step 1 of 2: Estimate the sum using rounded numbers.

Answer:

Answer :

To estimate the sum, we begin by rounding each number to the nearest whole number.

1. The number [tex]$$67.09$$[/tex] rounds to [tex]$$67.$$[/tex]
2. The number [tex]$$38.6$$[/tex] rounds to [tex]$$39.$$[/tex]
3. The number [tex]$$5.15$$[/tex] rounds to [tex]$$5.$$[/tex]

Now, we add the rounded numbers:

[tex]$$
67 + 39 + 5 = 111.
$$[/tex]

Thus, the estimated sum is [tex]$$111.$$[/tex]
