Answer :
3 1/4 = 13/4
12 pounds × 13/4 cups per pound = 39 cups
Each bird seeder holds 3/4 cup. So, how many times does 3/4 go into 39?
39 ÷ 3/4 is the same as 39 × 4/3. 39 × 4/3 = 52.
Therefore, the volunteer can fill 52 bird feeders.
12 pounds × 13/4 cups per pound = 39 cups
Each bird seeder holds 3/4 cup. So, how many times does 3/4 go into 39?
39 ÷ 3/4 is the same as 39 × 4/3. 39 × 4/3 = 52.
Therefore, the volunteer can fill 52 bird feeders.
If each pound contains 3 and 1/4 cups of seed, this means that in 12 pounds it has a total of 13 / 4x12 = 156/4 or a total of 39 cups of seed. If each bird feeder contains 3/4 cups of seed, and as mentioned in 39 cups has 156/4, then the number of bird feeders that can be filled completely with this amount of seed, gets (156/4) / (39/4) or only 156/39, which means 52 bird feeders.
Number of bird feeders that can be filled completely is 52.
