Three Fifths is not a whole number it's only 60% of a whole.
Well, two whole are 10 fifths, and add them to the 3 you allready have, you get 13 fifths.
Each "whole one" is made of 5 fifths. Therefore 5 whole ones will contain 25 fifths.
As a whole or of a whole?
There are five fifths in one whole.
four fifths must be added to make it whole
Four fifths is not a whole number so it is not possible to express it as a whole number.
Twenty fifths is 4 whole.
Two fifths, this is because 5 fifths is the whole and if you already have 3 fifths you just need 2 more to make 5.
One-fifth and four-fifths makes a whole.
Three-fifths is a fraction and there is no sensible way to represent it as a whole number. The whole part of it is 0.
5 fifths are in a whole (1). 75 fifths are in 15.
