Question

14．50×$\frac{1}{50}$=4×$\frac{1}{4}$=A（A不為0）×$\frac{1}{A}$=$\frac{11}{4}$×$\frac{4}{11}$．

Answer 1

分析 根據(jù)倒數(shù)的意義：乘積是1的兩個(gè)數(shù)叫做互為倒數(shù)；據(jù)此解答．

解答 解：50×$\frac{1}{50}$=1
4×$\frac{1}{4}$=1
A×$\frac{1}{A}$=1
$\frac{11}{4}$×$\frac{4}{11}$=1
故答案為：$\frac{1}{50}$，$\frac{1}{4}$，$\frac{1}{A}$，$\frac{11}{4}$．

點(diǎn)評(píng) 解答此題的關(guān)鍵是根據(jù)倒數(shù)的含義進(jìn)行解答即可．
