The  best way for you to answer this question is to change each of these fractions to decimal form.  Some people do not understand that every fraction can be made into a decimal because every fraction is a division problem.  Let's take 4/5 as an example.  If you divide 5 into 4, you will get 0.8 as an answer.  If you use this method to change every fraction to a decimal, you will be able to see which is the largest. 

It is important to understand the relationship between fractions and decimals because sometimes it is easier to think in decimal form and sometimes it is easier to think in fraction form, depending on our task. We all need to be able to move back and forth between them.  Take money, for example.  It is easier for us to calculate decimals when we are dealing with money. If we had to add or subtract in fractions, it would probably take longer.  But when we are cooking or baking, we use fractions because it would take us longer to figure out ingredients using decimals.  If you want to double a recipe that uses 1/3 cup of milk, you will be much happier calculating that 1/3 + 1/3 = 2/3 than you would calculating 0.33 + 0.33. 

Work on understanding this relationship, and you will be much more comfortable in the world of math and the world in which we need math. 

Good luck!
