Answer:
The answer is: 300,000
Explanation:
Hundred thousand is the natural number which follows 99,999 and 100,001.
Hence, the number is given by: 100,000.
Hence, when we round any number to the hundred thousand then there must be 5 zeros in the number.
i.e. the number 340,413 rounding to the nearest hundred thousand is given by: 300000
( Since the first digit i.e. 3 is at the hundred thousand place and all the number that precedes this place is converted to 0 )
