Pairs of Legs

Paul sent in a solution for this problem:

Seonaid and Brid from St Andrew's explained how they knew how many pairs of legs each creature has:

We worked out how many pairs of legs these creatures had by dividing the number of legs by two because there are two legs in a pair.

Juma from Ricards Lodge also explained her working out very clearly and used a method similar to Seonaid's and Brid's.
