(-5/12)×4/15×(-3/2)×(-6)
15+(-2)+5+(-1)+10+(-3)+(-2)+12+4+(-5)+6等于多少?
-12/5*15/8*(-2/3)*(-3/2)
分数简便运算(小学)12/5x(4/15+2/5)-3/5简便
括号里填什么:2,(),3,(),4,15,5,12,6,10
(√15+√12)÷√3x(√5-2)-4=?
①(-3)*(-5/6)*(-9/5)*1/4 ② 5/12 - 8/15 * 1/4 *(-3/2) ③(-5)* 8 *(-0.25)*(-7)
计算(能简算的要简算) 15/16-(2/3+1/4) 1/4-7/12+3/4-5/12
(5/12+2/3-3/4)x(-12)
(-12)*(-一有三分之四) 5/6*(-0.2) 12.*(-1.35)*(-40)*2-1-(-11/2)*(-4/11) (-5)/(-15)/(-3)
(1*3*5+2*6*10+3*9*15+4*12*20+5*15*25)/(1*2*3+2*4*6+3*6*9+4*8*12+5*10*15)等于多少?
(-5/12)×8/15×1/2×(-2/3);(-1)×(-5/4)×8/15×3/2×(-2/3)×0×(-1)还有一题:18-6÷(-2)×(-1/3)
(1/3/12+2/6/24+3/9/36+4/12/48)/(2/3/5+4/6/10+6/9/15+8/12/20)=?
(1/3/12+2/6/24+3/9/36+4/12/48)/(2/3/5+4/6/10+6/9/15+8/12/20)=?
P8~11(3)(4)(5)(7)(8)(10)(11)(12)(13)(15【2】)这几题的答案
能简算的要简算 (3)11/12×5/7+11/12×2/7 (4)7/8×15+7/8(3)11/12×5/7+11/12×2/7(4)7/8×15+7/8
{(4+3分之2)/2分之5}*12分之5 7/15÷14/3*6/5
想怎样简便就怎样简便 (1)2/3*5/16除5/3 (2)15-2.4除4/15 (3 )(5/6+1/4)除5/12(2)15-2.4除4/15 (3 )(5/6+1/4)除5/12一定要有过程
