45.7/6/3竖式这么列呀

45.7/6/3
=45.7/18
=457/180
=(360+97)/180
=2+97/180
≈2.54
商是2

22Ⅹ3/7一3/7=多少，竖式

22×7分之3-7分之3
=(21+1)×7分之3-7分之3
=21×7分之3+1×7分之3-7分之3
=9+(7分之3-7分之3)
=9

列竖式计算7/10-(3/4-3/10)

7/10-(3/4-3/10)
=7/10+ 3/10 -3/4
=1 -3/4
=1/4

三点2×3/8列竖式计算

3.2×3/8
=16/5×3/8
=2/5×3
=6/5
=1.2

8/11×3/4×33竖式列算怎么做

8/11x3/4x33
=8/11x33x3/4
=24x3/4
=18

(3/8 +6/7)-(0.125-1/7)=?

(3/8 +6/7)-(0.125-1/7)
=(3/8 +6/7)-(1/8-1/7)
=(3/8-1/8)+(6/7+1/7)
=1/4+1
=1又1/4

2/3/7/8/8/8/6/6/6/7/8/8/7/7x=9999999999 x=?

(-6.6)×3/7＋(-2.2)×3.7＋3.3×8/7
=(-6.6-2.2)×3.7+3.3×8/7
=-8.8×3/7＋3.3×8/7
=-3.3×8/7＋3.3×8/7
=0

(-5)*(-3/6/7)+(-7)*(-3/6/7)+12*(-3/6/7) 两个代表几又几分之几！

(-5)*(-3/6/7)+(-7)*(-3/6/7)+12*(-3/6/7)
=(-3/6/7)(-5-7+12)=(-3/6/7)*0=0

3/7乘12.5乘6/7乘8

因为12.5×8=100，
所以结果是，
写作1800/49。
