Anne has a 10 3/4 pounds bag of flour. each time she bakes a batch of rolls she uses 2 1/6 pounds of flour. how many pounds of flour remain after anne bakes 3 batches of rolls

If you would like to know how many pounds of flour remain after Anne bakes 3 batches of rolls and Anne has a 10 3/4 pounds bag of flour and each time she bakes one batch of rolls, she uses 2 1/6 pounds of flour, you can calculate this using the following steps:

for 3 batches of rolls, she needs:
3 * 2 1/6 = 3 * 13/6 = 13/2 = 6 1/2 pounds of flour

now, you have to subtract 10 3/4 and 6 1/2:
10 3/4 - 6 1/2 = 43/4 - 13/2 = 43/4 - 26/4 = 17/4 = 4 1/4 pounds of flour

Result: 4 1/4 pounds of flour remain after Anne bakes 3 batches of rolls.
