Answer:
The number was rounded to the nearest ten thousand.
Step-by-step explanation:
In situations when you don't need an exact result, you can round numbers. When you round numbers, you always round to a particular place value, such as the nearest ten thousand. If you round up or down it usually depends on which number is closest to your original number. When a number is exactly between two possible numbers, it is rounded to the largest number.
Rounding 710,430 to 700,000 means doing so to the nearest ten thousand.
In this case there was a reduction of 10,430 (710,430 - 700,000) because 10,430 is less than half of 100,000.
Hope this helps!
