Advice for comparing fractions:
Check the denominator- if they are the same it is as easy as counting 123.
Check the numerator- if they are the same then the bigger denominator, the smaller pieces of the fraction are.
Is one piece missing? What score would you rather have? 1/2, 2/3, 9/10, 19/20? If only one is missing the bigger the denominator, the greater the fraction's value.
Less than half, half, more than half- categorize your fractions in these groups and go from there.
