Describe Three Ways to Write Negative Fractions?
There are three different ways that a negative fraction can be written. They are all represent the same value. 1. The negative sign can be written to the left of the numerator.2. The negative sign can be written to the left of the denominator.3. The negative sign can be written to the left of the fraction bar. Examples:-1/4 = (-1)/4 = 1/(-4) is read" negative one fourth"-1/3 = (-1)/3 = 1(-3) is read" negative one third
Case 1: Suppose we have two terms 8ab and 4ab. On dividing the first by the second we have 8ab/4ab = 2 or 4ab/8ab = (1/2) depending on whether we consider either 8ab or 4ab as the
