Question

a. How many ducks are
in the pond?

. For every 3 ducks, there are 4 swans.
. For every 2 ducks and swans, there are 3 geese.
. There are 21 geese in the pond.

Answer 1

Well since there are 2 ducks for every 3 geese, and there are 21 geese in the pond, you would multiply 3 and 7, which equals 21. So then you would do the same with 2, which equals 14. So there would be a total of 14 ducks

Sorry if I’m wrong but hope this helps
