There is 5/6 of an apple pie left from dinner. Tomorrow, victor plans to eat 1/6 of the pie that was left. How much of the whole pie will be left after he eats tomorrow?
lets assume the whole pie is 1, that is all fractions added together have to sum 1. If Victor eats 1/6 out of 5/6, then the rest is 4/6 of the pie, that is the subtraction of those fractions.
