Descending means from the highest (largest) to the lowest (smallest) Before ordering, make sure the denominators are the same by following the steps below: 1. Find the L.C.M for the denominators of the fractions (20,25,100,4) 2. Multiply the numerator and the denominator of each of the fractions by the number whose multiplication with the denominator of that fraction gives the L.C.M 3. Once the denominators are the same, you can order the fractions using the value of the numerators 4. Once you've ordered them, replace the ordered fractions by their corresponding fractions given in the question
