2/3加括号5/8-1/6括号算式
2/3加括号5/8-1/6括号算式
简便计算
2/3+(5/8-1/6)
=2/3-1/6+5/8
=1/2+5/8
=9/8
括号5/8-1/10反括号X括号5/9+1/3反括号
=(25/40-4/40)×(5/9+3/9)=21/40×8/9=7/15
括号1/4-括号5/8-1/2括号括号除以1/24
[1/4-(5/8-1/2)]÷1/24
=(1/4-5/8+1/2)x24
=1/4x24-5/8x24+1/2x24
=6-15+12
=3
2/3×括号1-12.5%-5/8括号
2/3×(1-12.5%-5/8)
=2/3×(1-3/4)
=2/3×1/4
=1/6
括号5/6 2/9括号 除以括号5/6节2/9括号
计算过程
(5/6+2/9)/(5/6+2/9)=1
5/6+1/9=17/18
8/9乘大括号3/5加括号5/5减1/3括住括号,
8/9乘大括号3/5加括号5/5减1/3括住括号,
解:
8/9×[3/5+(5/5-1/3)]
=8/9×(3/5+2/3)
=8/9×19/15
=152/135
1/2加括号,负2/3反括号减括号负4/5放挂号加括号,负1/2反话
什么意思
5/8-括号3/8减1/6括号加5/6
5/8-(3/8-1/6)+5/6
=(5/8-3/8)+(5/6-1/6)
=2/8+4/6
=1/4+2/3
=3/12+8/12
=11/12
4/9加括号5/4-1/3括号。
4/9+(5/4-1/3)
=4/9+(15/12-4/12)
=4/9+11/12
=14/36+33/36
=47/36
=1又11/36
谢谢,请采纳
1/3加括号负5/6减块儿负1/2减2/3,
原式=-2/3-1/6+1/4-1/2 =1/4-(2/3+1/6+1/2) =1/4-(4/6+1/6+3/6) =1/4-4/3 =3/12-16/12 =-13/12。
