☆算术计算1题
〖1/1算式〗
作业:求算式 ((10.5%-4%)-(11%-4%)×0.5)/((10.5%-4%)+(11%-4%)-(10.5%+11%-2×4%)×0.5) 的值.
题型:数学计算
解:
((10.5%-4%)-(11%-4%)×0.5)/((10.5%-4%)+(11%-4%)-(10.5%+11%-2×4%)×0.5)
=(0.065-(11%-4%)×0.5)/((10.5%-4%)+(11%-4%)-(10.5%+11%-2×4%)×0.5)
=(0.065-0.07×0.5)/((10.5%-4%)+(11%-4%)-(10.5%+11%-2×4%)×0.5)
=0.03/((10.5%-4%)+(11%-4%)-(10.5%+11%-2×4%)×0.5)
=0.03/(0.065+(11%-4%)-(10.5%+11%-2×4%)×0.5)
=0.03/(0.065+0.07-(10.5%+11%-2×4%)×0.5)
=0.03/(0.065+0.07-0.135×0.5)
=0.03/0.0675
=0.444444 答案:((10.5%-4%)-(11%-4%)×0.5)/((10.5%-4%)+(11%-4%)-(10.5%+11%-2×4%)×0.5)=0.444444你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
