0.75+(-2 3/4)+(0.125)+(-12 5/7)+(-4
0.75+(-2 3/4)+(0.125)+(-12 5/7)+(-4
0.75+(-2 3/4)+(0.125)+(-12 5/7)+(-4 1/8)
=0.75+(-2.75)+(0.125)+(-12 5/7)+(-4.125)
=0.75-2.75+0.125-12 5/7-4.125
=(0.75-2.75)+(0.125-4.125)-12 5/7
=-2-4-12 5/7
=-6-12 5/7
=-18 5/7
(即-18又5/7,也可以化为-131/7)

1.计算 1又3/4-0.25 .0.125*2/3 .0.063*1/9.1又4/8-0.75.
简便计算 0.75+(2又3/4)+(+0.125)+(-12又5/7)+(-4又1/8)0.75+(2又3/4)+(+0.125)+(-12又5/7)+(-4又1/8)
0.75+(-2又4分之3)+0.125+12又7分之5+(-4又8分之1)等于多少
计算题:|-0.75|+(+3又1/4)-9-(-0.125)+(-5/8)-|-0.125|
几道数学计算题7/4÷7/8-2/3×(-6) -0.125÷1/4×(-8) (-10/3)×(-2.5)×4×(-3/10) (-5)×(-0.75)-(-5)×0.125+(-5)×(0.125)
0.75+(-3又4/3)+(+0.125)+(8又-7/6)+(-3又8/1)=
