Round 45,809 to nearest thousand and also round 26,789 to nearest ten thousand

45,809 rounded to the nearest thousand is 46,000.

26,789 rounded to the nearest ten thousand is 30,000

The nearest thousand would be the number to the left of the comma. So in this case it is the 5, this means that if it is 5 or more we raise the 5 to a 6 and make everything behind it a 0 or if it is 4 or less we keep it at 5 and make everything behind it 0.

So it would be 46,000 since it is an 8 and the next one would be 27,000 because the next number is 7.
