How do you arrange the fraction from greatest to least?

Answer 1

With certain fractions then experience and observation will enable them to be placed in descending order.

With fractions where the order is difficult to assess then they will need to be converted to equivalent fractions having the same denominator. A direct comparison of the numerators will then enable the original fractions to be placed in order.

EXAMPLE : Arrange 5/6. 8/9 and 7/8 in descending order.

The Lowest Common Multiple of 6, 8 and 9 is 72. This is the new common denominator.

5/6 is equivalent to 5x12/6x12 = 60/72 : 8/9 is equivalent to 8x8/9x8 = 64/72 : 7/8 is equivalent to 7x9/8x9 = 63/72.

Therefore the descending order is 64/72,63/72,60/72 or 8/9, 7/8, 5/6
