14-(4/3+3/4)÷8/5简便方法计算 =14-(4/3)×(5/8)-(3/4)×(5/8) =14-5/6-15/32 =13+1/6-15/32 =13+16/96-45/96 =12+67/96 =12又96分之67; 如果本题有什么不明白可以追问,如果满意记得采纳 如果有其他问题请采纳本题后另发点击向我求助,答题不...

14.5x5.8+3.9 =14.5x(6-0.2)+3.9 =14.5x6-14.5x0.2+3.9 =87-2.9+3.9 =87+(3.9-2.9) =87+1 =88 朋友,请及时采纳正确答案,下次还可能帮到您哦,您采纳正确答案,您也可以得到财富值,谢谢。

14.5×5.5+3.9 =14.5×5.5+1×5.5-1.6 =(14.5+1)×5.5-1.6 =15.5×5.5-1.6 =85.25-1.6 =83.65 满意请采纳,祝你学习进步!

14.8-4.8加括号分别乘0.5,再用14.8×0.5的结果减去4.8×0.5的结果就得出最后结果了。

14/0.5-14/3.5 =28-4 =24 如有帮助请采纳, 如对本题有疑问可追问,Good luck!

14.5+3.7+5.5 =(14.5+5.5)+3.7 =20+3.7 =23.7

5.14×3+97×5.14 =5.14x(3+97) =5.14x100 =514

7/8乘括号8+7括号乘5/14简便计算 =7/8x8x5/14+7/8x7x5/14 =7x5/14+7/8x5/2 =5/2+7/8x5/2 =5/2+35/16 =40/16+35/16 =75/16 =4又11/16

解: 14/9+9/14+5/9+5/14+8/9 =(14/9+5/9+8/9)+(9/14+5/14) =(14+5+8)/9+(9+5)/14 =27/9+14/14 =3+1 =4 (找分母相同 再把分子相加就可以计算了)
