97减去62.2加上22.2的简便算法

97-62.2+22.2 =97-(62.2-22.2) =97-40 =57

8.62加2.14减1.14减3.62简便运算 =8.62-3.62+(2.14-1.14) =5+1 =6

19.62-(2.68+2.97) =19.62 - 2.68 - 2.97 =19.62 + 0.06 - 0.06 - 2.68 - 2.97 =(19.68 - 2.68) - (2.97 + 0.03) - 0.03 =17 - 3 - 0.03 =14 - 0.03 =13.97 希望我的回答对您有帮助,满意请采纳,谢谢。

27.38减5.34加2.62减4.66 =(27.38+2.62)-(5.34+4.66) =30-10 =20 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。

8.62-2.98 =8.62-3+0.02 =5.62+0.02 =5.64

加法与减法互为逆运算 先看括号所处的位置,是加数,还是和,还是被减数,减数或差,然后用相应的加法和减法求解 本题中:括号处是减数,应该用被减数减去差可求的,62-2=60 谢谢,请采纳

300÷125÷8=300÷(125×8)=300÷1000=0.3 396-96-172-28 =(396-96)-(172+28)= 300-200 = 100 125*24 = 125*8*3 = 1000*3 = 3000 26*15 = (20+6)*15 = 20*15 + 6*15 = 300+90 =390 25*99*4 = 25*4*99 = 100*99 = 9900 250*32 = 250*4*8 = 100...

=(37.62-10.62)+(2.76+0.24) =27+3 =30

6.74-2.62-4.38+3.26 =(6.74+3.26)-(2.62+4.38) =10-7 =3

62Ⅹ102-63x2有没有简便算法 62Ⅹ102-63x2 =62*102-62*2-2 =62*(102-2)-2 =62*100-2 =6200-2 =6198
