conversion help?

[bugs2819]

Ive had trouble with this question and i need help.


A humming bird weighs .39 ounce; a blue whale weights 153.5 tons. How many humming birds does it take to equal the whale?


I know 16 oz. = 1 lb. and 2000 lbs. = 1 ton
but i still can't get the question

Why not?

You have the conversion factor for pounds and tons. So how many pounds is the whale?

You have the conversion factor for ounces and pounds. So how many ounces is the whale?

You then have the whale in terms of ounces, and the hummingbird in the same unit. How many 0.39-ounce birds can the whale's ounces be divided into?

Please reply showing your work and where you are getting stuck. Thank you.
