If a duck has 2 legs, how many legs in total are there in 5 ducks?
In this problem, use multiplication as your operation.
Solution:
   2 (leg of a duck)
x 5 (given quantity of duck)
=10 legs
To illustrate the problem:
Make 5 groups of two legs of a duck. Assume that each group is the duck (and {} as the leg of duck.)
({}{}) ({}{}) ({}{}) ({}{}) ({}{})
Now, count the number of legs {} in total, and it's 10.
