这三题,分别如上:

5.9×0.3-1.9×=0.6 解:1.77-1.9×=0.6

参考: 十七点五乘以八分之一加上零点二五乘以一点二五简算 七十七点五乘以八分之一加上零点二五乘以一点二五 =77.5x0.125+0.25x1.25 =77.5x0.125+2.5x0.125 =(77.5+2.5)x0.125 =80x0.125 =10

请改成阿拉伯数字,这么写看不懂运算顺序

负四点七五乘零点一二加五点九六除以括号负二点三四括号 =-4.75×0.12+5.96÷(-2.34) =-0.57-2.55 =-2.82; 请采纳 如果你认可我的回答,敬请及时采纳, ~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评...

5.8×(3.87-0.13)+4.2×3.7 =5.8×3.7+4.2×3.7 =(5.8+4.2)×3.7 =10×3.7 =37

1/3x0.3 =1/3x3/10=3/30=1/10 8/9x0.3 =8/9x3/10 =24/90 =4/15 3/5x25/100 =3/5x1/4 =3/20 ........

二点八加十八除以一点五减零点三乘零点五。 2.8+18÷1.5-0.3x0.5 =2.8+12-0.15 =14.8-0.15 =14.65

125*0.176+36.1/0.8+12.5*2.63 =0.125*176+361/8+0.125*263 =176/8+361/8+263/8 =(176+361+263)/8 =(170+360+260+10)/8 =800/8 =100

46.3*0.58+5.38*5.8-1*0.058 =0.58*46.3+0.58*53.8-0.58*0.1 =0.58*(46.3+53.8-0.1) =0.58*100 =58
