列竖式计算:19.8×3.5=16.8

19.8×3.5=69.3;(2)16.89×2.35≈39.69;(3)76.4÷5.4=14…8;

答:16   + 8―――――24――――

14/9÷23/7÷14/19 =14/9×7/23×19/14 =14/9×19/14×7/23 =19/9×7/23 =133/207 8/9-8/9x3/16 =8/9×(1-3/16) =8/9×13/16 =13/18

(16.8+1.47)÷0.7 =18.27÷0.7 =182.7÷7 =26.1 竖式见图:

=(16.8+2.2)-(3.5+6.5) =19-10 =9

看图

16.8÷24用竖式计算 16.8÷24=0.7 有用请采纳。

16.8 × 0.35 = 5.88
