4.8×1.25=6 ~回答完毕~ ~\(^o^)/~祝学习进步~~~

1.26*7.5*1.25 =1.26*0.75*100/8 =126*3/4*1/8 =31.5*3/8 =94.5/8 =11.8125

原式 =1.6x7.5x1.25 =0.2x8x7.5x1.25 =(0.2x7.5)x(8x1.25) =1.5x10 =15

5.2×10.1 =5.2×10+5.2×0.1 =52+0.52 =52.52

8.8×1.25 =1.1×(8×1.25) =1.1×10 =11 或者: 8.8×1.25 =(8+0.8)×1.25 =8×1.25+0.8×1.25 =10+1 =11

1.25×32×2.5 =(1.25×8)×(4×2.5) =10×10 =100 你好,本题已解答,如果满意 请点右上角“采纳答案”。

56x0.125 =(7x8)x0.125 =7x(8x0.125) =7x1 =7 希望能帮到你!

11.4+1.25×2.4 =11.4+1.25×8×0.3 =11.4+10×0.3 =11.4+3 =14.4

括号里的20-1点二五×0点八括起来除以一点九脱式计算 解: (20-1.25×0.8)÷1.9 =(20-1)÷1.9 =19÷1.9 =10
