there is five-fifths in one. ten-fifths in two, so there are five two-fifths in two.
To find out how many fifths are in two and two-fifths, we first need to convert the whole number, two, into fifths. Since one whole is equal to five fifths, two wholes would be equal to ten fifths. Adding the two-fifths gives us a total of twelve fifths in two and two-fifths.

One fifth PLUS two fifths = 3 fifths
