I need to to round 423,607,492 to the ten thousands. I then need to round it to the million. Can someone help me.
I will be happy to check your work.
Which numeral is in the ten-thousand place in this number?
Which numeral is in the million place?
Once you have those identified, you should have no problem. General rule: 5+ is rounded up; under 4 is rounded down. Right?
Give it a try and someone here will give you feedback on your work.
