Arrange six-eighths, five-eighths, three-eighths, and two eighths in descending order.
Before we work on ordering fractions, it’s just like adding and subtracting fractions, we need to check for a common denominator. In our case, each of these fractions have a denominator of eight. So we can move forward with ordering them because they all have the same denominator.
Our fractions are all have a denominator of eight, just like our circle here is divided into eight pieces. This is what six-eighths would look like represented in this circle; six of the eight pieces would be shaded. And five-eighths would look like this; only five pieces would be shaded. Here is what three-eighths would look like, and here is what two-eighths would look like.
What we can recognise is that when our fractions have a common denominator, the larger the numerator is going to be larger in value. Descending order will then be the largest numerators in your list down to the smallest numerators on your list, like this: six-eighths, five-eighths, three-eighths, two-eighths.
