Leslie wants to buy 110 cat toys. If there are 11 cat toys in each pack, how many packs of cat toys should Leslie buy?

Leslie should buy 10 packs of cat toys.

To see why, you can divide the total number of cat toys by the number of toys in each pack:

110 / 11 = 10

So Leslie needs to buy 10 packs of cat toys, with each pack containing 11 toys, for a total of 110 toys.
