When a question asks you to put some fractions in ascending order of size all you have to do is find the lowest common multiple in the denominators of the fractions and times the original numerator and denominator by the number needed to get to that common multiple.
1) 8/3 5/4 12/5 the lowest common multiple between these fractions is 60.
2) now we have to times the numerator and the denominators of the fractions to get to that LCM so 8/3 X 20= 160/60 5/4 X 15 = 75/60 12/5 X 12 = 144/60.
3) now remember to put the numbers from smallest to biggest if the question asks so so it'd be 5/4, 12/5 and 8/3
