if a 16 ounce nectar feeder concede about 80 hummingbirds a day how many hummingbirds would you expect to be able to feed with a
tekilochka [14]
In the given question, it is already given that the 16 ounce feeder can feed about 80 humming birds. It has to be found the number of birds that a 12 ounce feeder can feed.
Now coming back to the problem.
The number of humming birds that a 16 ounce feeder can feed = 80
The number of humming birds that 1 ounce feeder can feed = (80/16) * 1
                                                                                                 = 5 * 1
                                                                                                 = 5 birds
Then
The number of humming birds that a 12 ounce feeder can feed = (12 * 5) birds
                                                                                                       = 60 birds
So a 12 ounce feeder can feed 60 humming birds.
