Question

16．-$\frac{3}{5}$的相反數(shù)比-$\frac{4}{5}$的絕對(duì)值大$-\frac{1}{5}$．

Answer 1

分析 首先求得-$\frac{3}{5}$的相反數(shù)和-$\frac{4}{5}$的絕對(duì)值，然后再相減即可．

解答 解：-$\frac{3}{5}$的相反數(shù)是$\frac{3}{5}$，-$\frac{4}{5}$的絕對(duì)值是$\frac{4}{5}$，
$\frac{3}{5}-\frac{4}{5}$=$-\frac{1}{5}$．
故答案為：-$\frac{1}{5}$．

點(diǎn)評(píng) 本題主要考查的是有理數(shù)的減法、絕對(duì)值、相反數(shù)的定義，求得-$\frac{3}{5}$的相反數(shù)和-$\frac{4}{5}$的絕對(duì)值，然后再列式計(jì)算是解題的關(guān)鍵．
