A fair was attended by 834,009 people
Rounding up this number of people to nearest ten thousand.
9 has a 'ones' value
Going to the right from left:
Second last zero has a 'tens' value.
Third from last zero has a 'thousands' value
4 has 'ten thousands' value
Round up 4 and because it is less than five it converts to zero
This gives an answer of 830,000.
