5.|-7.2-(-6.4)| +(-0.4 - |0.4| )
6.-3又1/2 -【(-1又5/6)- |-1/6|】
1、|-0.25| - [+(-5.75)] + |0.1| - |-(+0.5)|
= 0.25+5.75+0.1+0.5
= 6.6
2、1又3/4 - 2又1/6 - 1.75 + 3又2/3
= 7/4-13/6-7/4+22/6
= 3/2
3、 3又1/4 + (-2又3/5) + (-5又3/4) + (-8又2/5)
= 13/4 - 13/5 - 23/4 - 42/5
= -5/2 - 11
= -27/2
4、(-62.84)- (+38.57)+(37.16)-(-32.57)
= -62.84 - 38.57 + 37.16 + 32.57
= -25.68 - 6
= -31.68
5、 |-7.2-(-6.4)| +(-0.4 - |0.4| )
= 0.8-0.8
= 0
6、-3又1/2 -[(-1又5/6)- |-1/6|]
= -7/2 -[-11/6-1/6]
= -7/2 + 2
= -3/2
= 0.25+5.75+0.1+0.5
= 6.6
2、1又3/4 - 2又1/6 - 1.75 + 3又2/3
= 7/4-13/6-7/4+22/6
= 3/2
3、 3又1/4 + (-2又3/5) + (-5又3/4) + (-8又2/5)
= 13/4 - 13/5 - 23/4 - 42/5
= -5/2 - 11
= -27/2
4、(-62.84)- (+38.57)+(37.16)-(-32.57)
= -62.84 - 38.57 + 37.16 + 32.57
= -25.68 - 6
= -31.68
5、 |-7.2-(-6.4)| +(-0.4 - |0.4| )
= 0.8-0.8
= 0
6、-3又1/2 -[(-1又5/6)- |-1/6|]
= -7/2 -[-11/6-1/6]
= -7/2 + 2
= -3/2
