Since 756,000. 6,000 from the 756000 is the thousands. Forexample. 756,000 will be the same since 0 is less than 5. So it will be rounded to zeros, which it already is. So it will be 756,000. Hopefully I helped.
The 6 in 756,000 is the thousands place, so we want to round that number. So if the digit is 5 or above, then go up one number. Because the 6 is 5 or above, it changes to 757,000
