What changes may occur if the given dollar will be rounded off to its nearest value. <span>There will only be 2 chances, the dollar will become smaller or bigger. Why? </span> Because in mathematical rules of rounding off numbers: number below 5 will be round down and 5 and up will be rounded up. For example: You have a bill of $6.79 since the number next to the decimal point in the right is 7, it will be rounded up to $7. <span>But if your bill is $6.25, it will be rounded down to $6.00 </span> I got this from a different brainy member
