A volunteer has 12 pounds of birdseed to put in bird feeders in all of thr city parks. there are 3 1/4 cups of bird seed in a pound and each bird feeder holds about 3/4 cup of bird seed. how many bird feeders can the volunteer fill completely?

Sagot :

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.

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.
