Question

if a humming bird were to get all of its food from a feeder then a 16 oz nectar feeder could feed about 80 humming birds a day how many humming birds would you expect to be able to feed with a 12 oz feeder?

Answer 1

I think about 60 cause 80 divided by 16=5x16=80 and 16-4=12=12x5=60.

Answer 2

we know that

using proportion

`(80)/(16) (humming\ birds)/(oz) =(x)/(12) (humming\ birds)/(oz)\\ \\ 80*12=16*x\\ \\ x=(80*12)/(16) \\ \\ x=60\ humming\ birds`

therefore

the answer is

`60\ humming\ birds`
