Call it 21 fifths minus 13 fifths, ie 8 fifths which is one-and-three-fifths
16/5 - 14/5 = 2/5
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
Ten one fifth means divide by five = 50 / 5 = 10 so four fifths = 4 x 10 = 40 Answer: 50 - 40 = 10
one fifth
