seven and two fifths
six and three-fifths
- 22/15
14 and 3/5
Three and four-fifths
1 1/5 + 3 2/5 + 4 1/5 = 8 4/5
The answer depends on two fifth of WHAT!
One fifth PLUS two fifths = 3 fifths
One fifth plus one fifth is two fifths (2/5).
(2/3) + (4/5) = 22/15 or 1.466 (repeating)
There is no "why", because two plus two IS, in fact, four.
two plus two just does equal four.
