The sum of 2/3 and 1/5 is 13/15.
I believe that it does equal one!
five and one third
That equals 3 thirds which is also equal to one.
Five eights plus two thirds minus one fourth is equal to 1.04
5/6
7/9
3/4
Two thirds
One third plus one third equals two thirds.
1 third plus one third =============== There are many other fraction combinations which equal two-thirds. One, for example, is one-half plus one-sixth.
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
8/15
