Convert the fractions so that they have the same denominator.
2, 3 and 4's LCM (lowest common multiple) is 12.
Divide 12 by the denominator of the simplified fraction for each one, then multiply the numerator by that to convert the fractions as such.
3/4 = (x3) 9/12
5/12
1/2 = (x6) 6/12
1/4 = (x3) 3/12
2/3 = (x4) 8/12
Now sort the fractions according to the numerator. You should get:
3/12, 5/12, 6/12, 8/12, 9/12
This is not the final step! Lastly, replace the converted fractions by their previous form:
1/4, 5/12, 1/2, 2/3, 3/4
Done.
