It is 1/5
negative 12 i guess
1 third plus one third =============== There are many other fraction combinations which equal two-thirds. One, for example, is one-half plus one-sixth.
less, if it is a fraction of a half, it cannt be a whole
One half is three sixths and one-third is two sixths. 3+2=5
One fourth plus one half plus one half plus 1 is equal to 2.25 or 2 1/4
Yes, they are are.
