since the ratio is 16:9 ducks to geese, there are 9 geese in every 25 birds. multiply 300 by 9/25. answer is 108.

169
Jam says:
you can use proportions for this
you have 9 geese for every 16 ducks,
find the amount of geese per amount of total birds
so that is 9/(9+16) = 9/25 9 geese for every 25 birds total
then you find how many geese there are for 300 birds
9/25 = x/300
multiply both sides by 300
(9/25)*300 = x
108 = x

Pi R Squared says:
Hi,
16 ducks + 9 geese = a group of 25 birds
That means 16/25 of all the birds will be ducks.
16/25 x 300 = 192 ducks and 108 geese < ==ANSWER
You could also do a proportion.
16. . . . x
—- = ——–
25. . . 300
25x = 16(300)
25x = 4800
x = 192 ducks, so 300 – 192 = 108 geese
I hope that helps!!
