希望我提供的对你有所帮助,有30道题并附答案,你就自己跳吧:0.72÷12=0.060.77÷1.1=0.70.72÷4=0.189.6÷6=1.64.6÷23=0.214÷0.5=286.8÷4=1
唉自己想吧
例1、3.6÷4= 84÷6= 10.5÷7= 6.3÷3= 10.5÷5=96÷8= 0.54÷9= 7.8÷6 例2、23.02÷1.6= 0.35÷0.014=
4.5×0.07=6.3÷0.09=2.5×3.6=19.8÷3.3=5÷0.25=0.76÷0.4=2.36×0.22=2.8×4.58=3.57÷4.2=82.8÷36=45×2.46=3.6÷0
1,梯形的中位线长为m,面积为S,则它的高为;2,在分式中,当y=时,分式没有意义;当y=时,分式值为0;3,当x=时,分式的值为0;4,某工厂原计划a天完成b件产品,若现在需要提前x天完成,则现在每
1.1/3*(5*(2/3))2.(1+37%)*203.35/2*75%4.30*(50/2)5.(54+10%)/206.(25/3*18)*30%7.(2+70%)*408.1/7*(98*(1
去掉小数点,用证书乘除法算,然后数小数点后一共有几位,由得到的答案向前移动几位,加小数点.
