You can put this solution on YOUR website! 1/2 for oranges
1/3 of 1/2 was left for mangoes or 1/6 of the total (multiply the two).
2/3 of 1/2 or 1/3 of the total or 2/6 of the total was given over to plantain.
mangoes is 1/2 that of plantain or (1/6)/(2/6)
The orange plantation is 5000 m^2, half of 10000 m^2.
He weeded 1/5 of the on the first day or (1/5)(5000)=1000 m^2 were weeded
so he has 5000-1000=4000m^2 left to weed.
