It means finding the lowest common denominator. So if your fraction is 10/32 (ten over thirty-two) you can reduce this by dividing the top and bottom by two. You'll get 5/16 (five over sixteen). There are no other numbers that you can evenly divide the top and bottom numbers by, so you have successfully reduced this fraction.
