Question

5．若乙數(shù)比甲數(shù)少$\frac{1}{6}$，則甲數(shù)比乙數(shù)多$\frac{1}{6}$．×．（判斷對(duì)錯(cuò)）

Answer 1

分析 根據(jù)題意知：乙數(shù)比甲數(shù)少$\frac{1}{6}$，則把甲數(shù)看作單位“1”，乙數(shù)是1$-\frac{1}{6}=\frac{5}{6}$，則甲數(shù)比乙數(shù)多幾分之幾，就要用甲數(shù)比乙數(shù)多的除以乙數(shù)．據(jù)此解答．

解答 解：1$-\frac{1}{6}=\frac{5}{6}$
（1$-\frac{5}{6}$）$÷\frac{5}{6}$
=$\frac{1}{6}÷\frac{5}{6}$
=$\frac{1}{5}$
答：則甲數(shù)比乙數(shù)多$\frac{1}{5}$．
故答案為：×．

點(diǎn)評(píng) 解答本題的關(guān)鍵是準(zhǔn)確理解題意，找到題目中的單位“1”．
