What 2793149 rounded to the nearest hundred thousand?

Answer 1

2,793,149 rounded to the nearest hundred thousand would be 2,800,000.

The "hundred-thousands" place is 7, and the next most significant digit is 9. If the next-most-significant digit is 4 or lower, we round down; if it's 5 or greater, we round up. Since the "next-most-significant digit" is 9, we round up from 7 to 8.
