Answer:
a. We need 1/4 for each feeder  
b. To fill each feeder we need 1.25 pounds
c.  We need 60 ounces to fill three bird feeders
Step-by-step explanation:
Five pounds of birdseed is used to fill 4 identical bird feeders,  
a. We divide all the birdseed in 4 feeders, so,  we need 1/4 for each feeder. 
b. If we use 5 pounds for the 4 feeders,  so each feeders will take 1/4 of the 5 pounds 
 =1/4 x 5=1.25 pounds
c. To fill three bird feeders we have to multiply the amount of pounds by feeder by 3 feeders 
=1.25 pounds x 3
= 3,75 pounds
If 16 ounces are a pound 
so,  16 x 3.75 = 60 ounces
