How many 6 bottle packages of bottled water must Rashmi's mom buy if she plans to serve 1 bottle to each of the 28 people who will attend the school fair?

You will want to divide 28 by 6 which will give you 4 remainder 4 which means that she will need 5 packages of water bottles for everyone to have one but once everyone at the school fair gets a water bottle there will be a few water bottles left over

If she plans to serve 1 bottle to 28 people and there is 6 water bottles in each package she will have to buy 5 packages and have 2 leftover.
