6.09

0.63 × 1.05 = 0.6615 竖式见图:

3.03×1.5=4.545 3.03 × 1.5 ———— 1515 303 ———— 4.545

就是15除以70

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

2.02×8.5 =2×8.5+0.02×8.5 =17+0.17 =17.17 3.4×7×1.5 =(3.4×1.5)×7 =5.1×7 =35.7

7.05×1.95=13.7475 回答完毕~~ 有疑问请追问,无疑问请点击【采纳】~ 祝学习进步~~~\(^o^)/~
