Question

Compare the values of each of the following pairs of fractions by expanding the fractions

Answer 1

We'll need to find and use the LCD here. The LCD is 7(9), or 63. Then this set of fractions becomes

{81/7, 77/7}. The former (first) fraction is the larger one: 81/7 > 77/7, so

9/7 > 11/9.
