Five pounds of birdseed is used to fill 4 identical bird feeders.
enyata [817]

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
