There are 4 animals in an enclosure. Some are geese and the others are boars. Andy counts a total of 14 legs.
- How many boar are there?
- How many geese are there?
(a)
If all of the animals are geese,
number of legs needed for geese
= 4 x 2
= 8
Extra legs needed for each boar
= 4 - 2
= 2
Total extra legs needed for all the boar
= 14 - 8
= 6
Number of boar
= 6 ÷ 2
= 3
(b)
Number of geese
= 4 - 3
= 1
Answer(s): (a) 3; (b) 1
