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.
