At-large is a designation for members of a governing body who are elected to represent the whole membership of the body like for example a state, club, city
At-large voting is in contrast to voting by electoral districts.
It is a bit confusing on why you said 40,0000 with four zeros
But based my assumptions with calculations, here are my answers:
40,0000 with five zeros or 400,000÷60=6666.67
40,000 with four zeros=666.67
What word? Provide with more info please!
