Respuesta :

The number of acres of land are planted with oranges is 10

What is the size of the farmland?

The size of the entire farmland can be represented by X, which means that he planted coconuts of 3/8*X

The portion left after planting coconuts is expressed thus:

X=3X/8=5X/8

The portion planted with oranges is 4/5 of 5X/8

5X/8-(4/5*5X/8)=2.5

5X/8-4X/8=2.5

5X-4X/8=2.5

X/8=2.5

X=2.5*8

X=20 acres ( in all)

Portion planted with coconuts=3/8*20

Portion planted with coconuts=7.5

The number of acres left after planting coconuts=20-7.5

The number of acres left after planting coconuts=12.5

portion planted with oranges=4/5*12.5

portion planted with oranges=10 acres
