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%,

Answer:
68 plants.
Step-by-step explanation:
Let x represent the number of plants that Reuben bought from the nursery.
We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be .
We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be .
Further a rabbit came and ate ½ of what was left. So number of plants left would be .
Since Reuben had only 7 plants left, so we will equate our expression with 7 and solve for x as:
Therefore, Reuben bought 68 plants at the nursery.
