Answer 1

分析 先算乘法，再算除法，再算加法，最后算減法，求出結(jié)果，然后再進(jìn)一步解答．

解答 解：$\frac{1}{5}$×$\frac{1}{5}$÷$\frac{1}{5}$÷$\frac{1}{5}$+$\frac{1}{5}$-$\frac{1}{5}$
=$\frac{1}{25}$÷$\frac{1}{5}$÷$\frac{1}{5}$+$\frac{1}{5}$-$\frac{1}{5}$
=$\frac{1}{5}$÷$\frac{1}{5}$+$\frac{1}{5}$-$\frac{1}{5}$
=1+$\frac{1}{5}$-$\frac{1}{5}$
=1$\frac{1}{5}$-$\frac{1}{5}$
=1．
故答案為：×．
