Since five fifths equal one whole, 6/5 would equal one whole plus one fifth. So 7 plus 1 and one fifth is 8 and 1 fifth or 8 1/5
7
6/7 minus 1/5 is 23/35.
Expressed as a mixed number, 15/7 is equal to 2 1/7 or two and one seventh.
Assuming twentithes was meant to be twentieths, 7/20 + 1/5 = 7/20 + 4/20 = 11/20
