Answer:
67900
Explanation:
We know that in order to round to the nearest 100 we need to look at the tens digit and if it is greater than or equal to 5 then we round up and if it is less than 5 we round down.
67948
The tens digit of this number is 4 and since we know that 4 is less than 5 we will round down to get our answer of 67900.
