Question

If a bird had 20 thousand feathers and each feather weighed 0.35 grams how many POUNDS would the frathers weigh.

(Don't worry about the weight of the actual bird)

Answer 1

So multiply 20000 by 0.35, and you get 7000 grams.
With a gram to pound conversion (about 1 gram = 0.022 pounds), you'll get
about 15.43 pounds...
