There are 6 animals in an enclosure. Some are lovebirds and the others are boars. Andy counts a total of 18 legs.
- How many boar are there?
- How many lovebirds are there?
(a)
If all of the animals are lovebirds,
number of legs needed for lovebirds
= 6 x 2
= 12
Extra legs needed for each boar
= 4 - 2
= 2
Total extra legs needed for all the boar
= 18 - 12
= 6
Number of boar
= 6 ÷ 2
= 3
(b)
Number of lovebirds
= 6 - 3
= 3
Answer(s): (a) 3; (b) 3
