0.67×1.9 0.33×1.9脱式计算

0.67x1.9+0.33x1.9 =(0.67+0.33)x1.9 =1x1.9 =1.9

解答:解:0.77+0.33=1.1 7÷1.4=5 9+29=929 1-0.09=0.91 5656÷56=101 32÷53×0=031÷1000=0.031 2.6-1.7=0.9 23÷7=221 15×50=750 0.12×100=1 1-16+56=53

3.18-(0.33+1.18) =3.18-1.18-0.33 =2-0.33 =1.67 朋友,请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果没有明白,请追问。谢谢。
