4÷0.25 3/4+0.25的和除以2又1/3+7/10等于多少

3/4+0.25的和除以2又1/3+7/10等于多少  

3/4+0.25的和除以2又1/3+7/10等于多少

3/4+0.25的和除以2又1/3+7/10
=1÷(7/3)+10/7
=3/7+10/7
=13/7
=1又7分之6

四又3/7加2.8减3/7等于？一除以1/10减1/10除以一=?

4+3/7+2.8-3/7
=31/7+14/5-3/7
=28/7+14/5
=4+14/5
=4+2+4/5
=6+4/5
1÷1/10-1/10÷1
=1×10-1/10
=9+9/10

10又3/4 0.25-1/7等于多少

10又3/4+0.25-1/7
=11-1/7
=10又6/7

0.25除以1/7+4分之1×2点3+7/10乘25%

0.25÷1/7+4分之1×2.3+7/10×25%
=0.25×7+0.25×2.3+0.25×0.7
=0.25×（7+2.3+0.7）
=0.25×10
=2.5

0.064^-1/3-(-1/8)^0+16^3/4+0.25^1/2 等于多少 最好有过程

0.064^-1/3-(-1/8)^0+16^3/4+0.25^1/2
=1/0.4-1+8+0.5
=2.5-1+8+0.5
=10

3/7*1/4+0.25*2/7+0.25*1/7怎么算

3/7*1/4+0.25*2/7+0.25*1/7
=3/7*0.25+0.25*2/7+0.25*1/7
=0.25x(3/7+2/7+1/7)
=0.25x6/7
=(0.25x6)/7
=1.5/7
=3/14

6又1/2-6、3x[（10-3又1/2）除以6、5]除以1又4/5等于多少？

6又1/2-6=1/2
3x[（10-3又1/2）除以6]=5-3又1/4
5除以1又4/5=25/9
我有没有算错哦？

3/5÷4+5又2/5×1/4+0.25

4又3/5÷4+5又2/5×1/4+0.25
=(4又3/5+5又2/5+1）×1/4
=11×1/4
=2.75
1998又1998/1999÷1998
=1998÷1998+1998/1999÷1998
=1+1/1999
=1又1/1999
2/5×60%+19/20×2/5+19/20+60%
=2/5×60%+19/20×（2/5+60%）
=0.24+19/20
=1.19
（9/5+8/3）÷[（4-11/6）÷13/4]
=67/15÷[13/6÷13/4]
=67/15÷2/3
=6.7

3/4+0.25÷(2/3-1.5*1/3)

3/4+0.25÷(2/3-1.5*1/3)
=3/4+0.25÷[(2-1.5)/3]
=3/4+0.25÷(0.5/3)
=3/4+0.25÷0.5*3
=0.75+1.5
=2.25

（-0.25）除以（-2/3）*(-3/2)/*4/9 等于?
