87 + 34
87 rounded = 90
34 rounded = 35
90 + 35 = 125
or
87 rounded = 90
34 rounded = 30
90 + 30 = 120
when rounding you are only getting an estimate so it is not going to be exact however you do it.
Answer: sum = 1200.
Step-by-step explanation:
Since we have two digits are numbers are given ,
So the only possible rounding or estimation will be done nearest to ones .
Rounding integers to nearest ones ,
[tex]87\text{ changes to }90\\34\text{ changes to }30\\[/tex]
So,
Sum is given by
[tex]90+30=1200[/tex]
So, our sum will be 1200.
