90,000. In 89,891, the 8 farthest to the left is in the place you want to round, and the 9 right next to it tells you the 8 needs to round up
Ok so you round 31 to 30 and 43 to 40 and then you multiply 30 by 40 and get 1200. 1200 is the same thing as 1200.00 bc you can take off the zeros after the decimal and it will be the same. Hope this helped and if your still confused you let me know I'll try to explain it more.
