5+0÷5-5=4.8÷0.01=0.8×0.125=2.5×0.4÷2.5×0.4=
1÷0.5=1÷0.1-9×0.1=3.75×99+3.75=(9.7-9.7)×3.77=

解:5+0÷5-5=0,4.8÷0.01=480,0.8×0.125=0.1,2.5×0.4÷2.5×0.4=0.16,
1÷0.5=2,1÷0.1-9×0.1=9.1,3.75×99+3.75=375,(9.7-9.7)×3.77=0.

故答案為:0,480,0.1,0.16,2,9.1,375,0.


分析:5+0÷5-5,先算除法,再算加法,最后算減法;2.5×0.4÷2.5×0.4按照從左到右的順序計(jì)算;1÷0.1-9×0.1先同時運(yùn)算乘法和除法,再算減法;3.75×99+3.75運(yùn)用乘法分配律簡算;(9.7-9.7)×3.77先算減法,再算乘法;其他題目根據(jù)運(yùn)算法則直接求解.
點(diǎn)評:本題考查了基本的運(yùn)算,注意使用簡便的方法提高速度和準(zhǔn)確性.
