Question

17．梨樹(shù)的棵數(shù)是桃樹(shù)的$\frac{7}{8}$，把桃樹(shù)的棵數(shù)看作單位“1”，桃樹(shù)的棵數(shù)×$\frac{7}{8}$=梨樹(shù)的棵數(shù)．

Answer 1

分析 根據(jù)判斷單位“1”的方法：一般是把“比、占、是、相當(dāng)于”后面的量看作單位“1”，即分?jǐn)?shù)“的”字前面的量看作單位“1”，可知是把桃樹(shù)的棵數(shù)看作單位“1”，桃樹(shù)的棵數(shù)×$\frac{7}{8}$=梨樹(shù)的棵數(shù)．據(jù)此解答．

解答 解：梨樹(shù)的棵數(shù)是桃樹(shù)的$\frac{7}{8}$，把桃樹(shù)的棵數(shù)看作單位“1”，桃樹(shù)的棵數(shù)×$\frac{7}{8}$=梨樹(shù)的棵數(shù)．
故答案為：桃樹(shù)，桃樹(shù)的棵數(shù)，梨樹(shù)的棵數(shù)．

點(diǎn)評(píng) 此題解答關(guān)鍵是確定單位“1”，一般情況把被比的數(shù)量看作單位“1”．
