four fifths must be added to make it whole
Two fifths, this is because 5 fifths is the whole and if you already have 3 fifths you just need 2 more to make 5.
2/5+3/5 = 1
Well, two whole are 10 fifths, and add them to the 3 you allready have, you get 13 fifths.

The answer to one half times five and three fifths is 2.8. To make it easier, take the fraction of three fifths, and convert it into decimal form, which is 0.6. Add 5 to that. Take the fraction of one half and convert that into decimal form, which is 0.5. Now multiply 0.5 and 5.6, and you get your answer.
three if the question was How many 1/3 make a whole
