Answer: 105 packs

Step-by-step explanation: The correct answer is 105 packs of table tennis balls. You need a total of 626 balls, so you divide this by 6 because that is what a standard package contains. The formula is 626/6 = 104.3. You will need 104 packs plus .3 of a pack, which means that you need to round it up to 105 packs of table tennis balls.
