Explanation:
Hi,
Think about it this way.
20%
40%
60%
80%
100%
We had to add 20% 5 times in order to get 100%.
The same goes for the fraction.
1/5
2/5
3/5
4/5
5/5
We had to add 1/5 5 times to get it to 5/5.
So...
20% is the same thing as... 20/100 and simplified, it's the exact same thing as 1/5.
They're basically the same exact thing except they're written in different ways.
I hope this helps, I didn't really understand what you needed exactly, but if you need anything else, feel free to let me know :)
Have a wonderful day.
