How 0.8, 8/10, 80/100, ⅘ and 80% are the same thing.

In this blog I am going to explain how 0.8, 8/10, 80/100, ⅘ and 80% are the same thing.

In the table below 80 out of the 100 spaces have been filled in. You can also write that as 80/100.





































































































I have divided this next table into ten columns or tenths.8 of these 10 or 8/10 are shaded in. It is still the same as in the table above.




































































































This third table has been divided into 5 groups or fifths. Four of the five columns are shaded in which makes it ⅘, as you can see it is still the same amount of squares shaded in as the 80/100 and the ⅘ above.





































































































For percentage and decimals, we are going to use the first picture we used. Because we have shaded in 8 tenths or 8/10 we know that if we put that 8 in the tenths column it will end up as 0.8. Percent is a number out of 100 so 80/100 is just 80%.
