Solution
In order to find greatest to least number, we have to convert the given fractions into decimals.
3
% = 3 + 1/10 = 3 + 0.10 = 3.10%
3
% = 3 + 2/5 = 3 + 0.40 = 3.40%
3
%= 3 + 0.25 = 3.25%
3
% = 3 + 0.33 = 3.33%
Now we can easily, compare the numbers and write from greatest to least.
3.40%, 3.33%, 3.25%, 3.10%
Greatest to least = 3 2/5%, 3 1/3%3, 3 1/4%, 1/10%,
