Our teacher had1/2 of an eraser left.she gave that to her 2 students equally.how much of the eraser did every student take home
iogann1982 [59]
Hello,

If the teacher has 1/2 of an eraser, and she divides it into 2 pieces to give 1 to each of her students, she gives (1/2) / 2 = (1/2) * (1/2) = 1/4 of the eraser to each student.

Each student takes home 1/4 of the eraser.

Hope this helps!
