None of these three fractions has a value greater than 3/4. If you solve these fractions to find their respective decimals, we get
3/4 = 0.75
1/2 = 0.5
1/4 = 0.25
1/5 = 0.2
As we can see, the decimal value of 3/4 (0.75) is the greatest on this list, therefore none of the other fractions has a value greater than 3/4.
Hope that helped =)
