Specify three fractions with different denominators that have a lcd of 24 then arrange the fractions in order from least to greatest.

We can just guess  20/24,     10 / 24   and 8 / 24

From the least to the greatest:

8/24, 10/24,    20/24

8/24 = 1/3            10/24 = 5/12            20/24 = 5/6

So it is:

1/3,  5/12, 5/6

I hope this helps.
