Assuming that you mean "fifths", the answer is three fifths.
Subtracting one fifth from one gives 1 - 1/5 = 4/5, or four fifths.
One whole minus two fifths is three fifths.
Call it 21 fifths minus 13 fifths, ie 8 fifths which is one-and-three-fifths
10 and 2/5
16/5 - 14/5 = 2/5
1 and 4 fifths.
Fourteen and four fifths.
We convert it into thirty-fifths. That gives 15 thirty-fifths minus 14 thirty-fifths which is one thirty fifth.
no four fifths is one fifth less than five fifths
Twenty four fifths is four and four fifths. So if you take three away, that leaves one and four fifths.
One-fifth and four-fifths makes a whole.
Ten one fifth means divide by five = 50 / 5 = 10 so four fifths = 4 x 10 = 40 Answer: 50 - 40 = 10
Three and four-fifths
4/5 minus 1/5 = 3/5
Sixteen fifths or 3 and one fifth.
