A coffee plantation is divided into blocks. Each block is 2/5 of an hectares. If the total area of the plantation is 12 hectares, how many blocks are there?
1 answer
If each block is 2/5 of a hectare, then the total number of blocks is 12 hectares / (2/5) hectares/block = 12*(5/2) = <<12*(5/2)=30>>30 blocks. Answer: \boxed{30}.
