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?
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}.
To find the number of blocks, divide the total area of the plantation by the area of each block.
Total area of the plantation = 12 hectares
Area of each block = 2/5 hectares
Number of blocks = (Total area of the plantation) / (Area of each block)
Number of blocks = 12 hectares / (2/5 hectares)
To divide a fraction by a fraction, we can multiply by the reciprocal of the divisor.
Number of blocks = 12 hectares * (5/2 hectares)
Multiply the numerators and denominators:
Number of blocks = (12 * 5) / (1 * 2)
Number of blocks = 60 / 2
Number of blocks = 30 blocks
Therefore, there are 30 blocks in the coffee plantation.
