Jorge want to write 4/5 as a sum of unit fraction. What should he write?

A unit fraction is a fraction where the denominator is one, so the easiest way to write 4/5 as a sum of unit fractions is to use 1/5. So the answer would be 1/5+1/5+1/5+1/5. Add up all the numerators and put that over their like denominators to get 4/5
