You need 46 paper plates for a party. The store only sells packs of
10 plates. How many pack of plates
will you need to buy?

So you need 46 which means that you can’t have less than 46 otherwise you won’t have enough
46/10 = 4 packs + 6 more plates
If you only buy 4 packs you will have 40 plates but you need 46 so buy an extra pack.
So you will need to buy 5 packs of plates.

I hope this helps :)
