Mrs. helio has 2 3/4 acres of farmland. she will plant corn on 1/4 of this land, potatoes on 1/12 of the land, wheat on 5/8 of the land and beans on the rest of the land. mrs. hello is thinking about planting less wheatvand more potatoes. if she changes the number of acres used for wheat to 1 1/2, how many acres will be left for the potatoes
