Carlos owns chickens. He feeds this 9 chickens 2 1/4 pounds of grain a day. How many pounds does each (one) chicken get?

Answer 1

Unit rate is done by dividing. 50 miles in 2 hours = 50 miles/2hours = 25 mph.

2 1/4 = 9/4

9/4 lbs/9 chickens = (9/4)(1/9) = 9/36 = 1/4 lb per chicken

Answer 2

Use a ratio:

9 chickens/2.25 lbs = 1 chicken/x lbs or 2.25 lbs/9 chickens = x lbs/1 chickens

x = .25 lbs = (1/4) lbs/chicken
