On the application of fractional equation In order to maintain the balance between food production and natural ecology, China began to implement the policy of "returning farmland to forest" in 2000. In small villages, the original cultivated land is 600 hectares and the forest land is 150 hectares. It is planned to turn part of the cultivated land into forest land, so that the forest land area accounts for 80% of the cultivated land area?
