15+(-1/4)-15-(-0.25) 8-2×3 3-(-0.25)-2-12-(-1/3-1/4+1/2)要写解 要写递等式计算
15+(-1/4)-15-(-0.25) 8-2×3 3-(-0.25)
-2-12-(-1/3-1/4+1/2)
要写解 要写递等式计算
15+(-1/4)-15-(-0.25) 8-2×3 3-(-0.25)-2-12-(-1/3-1/4+1/2)要写解 要写递等式计算
(1)原式=(15-15)-(1/4-0.25)
=0-0
=0
(2)原式=8-66+0.25
=-58+0.25
=-57.75
(3) 原式=-2-12-(-4-3+6)/12
=-2-12-(-1/12)
=-2-12+1/12
=-167/12

(0.5+0.25+0.125)/(0.5*0.25*0.125)*7/18*9/2+1/6/131/3-15/4*16/5
5分之4乘(2分之15+0.25)
5分之4×(2分之15+0.25)
5分之4*(2分之15+0.25)
{15/29 - (0.25+1/3)*7.2}/14/5
简算:1/12*0.25*72÷1/4 1/15÷23+1/23*14/15 35/32÷(1/8+3/4)*32
①(-3)*(-5/6)*(-9/5)*1/4 ② 5/12 - 8/15 * 1/4 *(-3/2) ③(-5)* 8 *(-0.25)*(-7)
15+(-4分之1)-15-(-0.25)
用简便运算: ①71又16/15*(-8) ②(-370)*(-4/1)+0.25*24.5+(+5又2/1)*4/1
():4=多少分之12=0.25=15除()=()填整数
(1)999*1999、(2)(1/15+2/17)*15*17,(3)20000/12.5/25/0.8/4 (4)38*1/4+17*0.25+45*25%
(0.25-x) ×(-36)=15 怎么计算?(0.25-x) ×(-36)=15 怎么计算?
脱式计算.(能简算要简算.) 9-(6分之1-0.125)*24 9分之4*15+9分之5除15分之1(3-0.25)除(4分之1+2)
