85.3+0.125x7.8x8的简便算法

85.3+0.125x7.8x8 = 85.3+0.125x8x7.8 = 85.3+1 x7.8 = 85.3+7.8 = 93.1

85.3+0.125*7.8*8 =85.3+(0.125×8)*7.8 =85.3+7.8 =93.1

85×1.1=85×(1+0.1)=85+8.5=93.5 0.125×7.9×8= 0.125×8×7.9=1×7.9=7.9 6.3÷35=6.3÷7÷5=0.9÷5=0.18 3.72x1.8十8.2×3.72 =3.72×(1.8+8.2)=3.72×10=37.2 ~如果你认可我的回答,请及时点击【采纳为满意回答】按钮~ ~手机提问的朋友在客户端右上角...

3.27×8.5+67.3×0.85 =3.27×8.5+6.73×8.5 =(3.27+6.73)×8.5 =10×8.5 =85

(1)12.25-3.1+0.85-6.17,=(12.25+0.85)-3.1-6.17,=13.1-3.1-6.17,=3.83;(2)2.65×1.7+1.35×1.7,=(2.65+1.35)×1.7,=4×1.7,=6.8;(3)3.6÷(1.2+0.5)×5,=3.6÷1.7×5,= 36 17 ×5,= 10 10 17 ; (4)0.125×0.38×80,=(0.125×80...

123×3+85×123 =(85+3)×123 =88×123 =10824

32.7x0.85+67.3×0.85 =(32.7+67.3)x0.85 =100x0.85 =85 3.2x(4.7+7.8) =3.2x12.5 =4x0.8x12.5 =4x10 =40 行家正解,不明白可以追问!祝您学习进步 满意请点击下面的【选为满意回答】按钮,O(∩_∩)O谢谢
