Question

Sarah raises rabbits. She uses 3/2 cups of pellets a day to feed 6 rabbits.

Part A - What is the unit rate of cups of pellets per rabbit? Show or explain your work.
Part B - There is 1/2 cups of pellets per 3/8 pound of pellets. What is the unit rate of cups of pellets per pound? Show or explain your work.

Answer 1

Part A. To find "pellets per rabbit", you divide the quantity of pellets by the corresponding number of rabbits.
(3/2 cups/day)/(6 rabbits) = 3/12 cups/day/rabbit
= 1/4 cup/day per rabbit

Part B. Same deal: to find cups per pound, divide cups by pounds.
(1/2 cups)/(3/8 pounds) = (1/2*8/3) cups/pound = 4/3 cups/pound
