Answer:
190,000.
Step-by-step explanation:
We are asked to estimate the sum of 137,638 plus 52,091.
First of all, we will round both digits to nearest ten thousands as:
[tex]137,638\approx 140,000[/tex]
[tex]52,091\approx 50,000[/tex]
Add both numbers:
[tex]140,000+50,000=190,000[/tex]
Therefore, our required sum would be 190,000.
