, , ,
You don't have to figure out the exact decimal values of the fractions in order to solve this problem. Written as a mixed number, .
You can see that is the lowest number, because is less than , and and are greater than .
Next comes , because a larger denominator means a smaller number (if, of course, the numerator is the same).
Then comes , and finally , which in decimal form (remember: "percent" = "per hundred") equals , which is clearly greater than .
