So the whole no. Is divided in 5 equal parts so its 5 parts out of 5 or 5/5.
If yvonne used 20 cups dividing by 5 we have as a result no. 4.
That means that from the whole 5/5 she used 4 parts (each 5cups)... and that is 4/5 ( simply said she used 4 parts out of total 5) . As info that means 80% of the total cups were used.
So 5/5 is the fraction for the 25 cups And 4/5 is the fraction of the ised 20 cups.
