Hi. To round this number to the nearest 1000 we count from the right...
4 is in the ones place
5 is in the tens place
6 is in the hundreds place
3 is in the thousands place
Okay, 3 is in the thousands place so you look to the right of that and if the number is 5 or higher we round up. The number to the right is a 6 so we round up and place zeroes for the remaining numbers so your final answer is:
7,434,000
I hope this helps. If you have any questions, please don't hesitate to ask.
Take care,
Diana
