0.8 8/10 ⅘ and 80% are all the same. Heres how.
This is a table that shows 0.8 which means 8 tenths in decimal form

Now here is a table that shows 80% 

As you can see the table for 80% and 8/10s is the same as 0.8

Now we will do ⅘ 

If we take 4 of these fifths then it will be the same as all the other tables. 

THE END!!
