The greatest fraction is 1/2.
Explanation:
1/2= 30/60
1/3= 20/60
1/4= 15/60
1/5= 12/60
(Remember, these I made each fraction another fraction that is equivalent to the point where they all have same denominators)
We can see that 1/2 is the greates out of all of them.
Shorter explanation, i think we all know that 1/2 is greater because if u have fractions with the same numerator, the fraction with the smallest denominator is the greatest fraction.
