Answer:
270,000
Explanation:
The ten-thousandths place is the fifth digit to the left of the decimal point, which is a 7 in this case.
The next number to the right of the 7 is a 4, which is 4 or less, so you don't need to round up the 7. This means we can just replace the 4 and everything to the right of it with 0s.
If the 4 were 5 or more instead, you would turn the 7 into an 8 and then turn everything after it into 0s.
