0.125*4.8 4.6/(2.3*0.4) 5.6/3.5+4.7 7.5*[63.9/(7-2.5)] 5.5*8+4.5/0.125 怎么简便计算
还有一道!26.19+0.91/(3.6-2.9)
各位,帮帮忙吧!
要脱式的简便计算!!!!!!!!

0.125*4.8
=0.125*8*0.6
=1*0.6
=0.6
4.6/(2.3*0.4)
=4.6/（4.6*0.2）
=1/0.2
=5
5.6/3.5+4.7
=0.7*8/（0.7*5）+4.7
=1.6+4.7
=6.3
7.5*[63.9/(7-2.5)]
=7.5*9*7.1/4.5
=0.5*15*9*7.1/（0.5*9）
=15*7.1
=106.5
5.5*8+4.5/0.125
=5.5*8+4.5*8
=（5.5+4.5）*8
=10*8
=80
26.19+0.91/(3.6-2.9)
=26.19+0.91/0.7
=26.19+1.3
=27.49
=0.125*8*0.6
=1*0.6
=0.6
4.6/(2.3*0.4)
=4.6/（4.6*0.2）
=1/0.2

0.125*4.8 4.6/(2.3*0.4) 5.6/3.5+4.7 7.5*[63.9/(7-2.5)] 5.5*8
简便计算：5.6*8+4.5/0.25=?7.5*【63.9/（7-2.5）】=?5.5*8+4.5/0.125=?26
7.5*[63.9/(7-2.5)简便计算
简便计算:7.5*[63.9/(7-2.5)]
(9.1×7.5×4.6)÷(1.3×2.5×2.3)简便计算
7.5×【63.9÷(7-2.5)】简便计算,只需要3-5步的
7.5×[63.9÷(7-2.5)]简便计算 26.19＋0.91÷(3.6-2.9)
计算7.5*2.3+2.9*2.5+12.5*0.4怎样算简便?
2.5*4.8*0.125巧算
1.2.3 4.6.11 5.6.7 1.5/2.5/4.5
(-5.5)-(-3.2)-(-2.5)-(-4.8) (2-7)-(3-9) (-18)+2
0.5+1.5+2.5+3.5+4.5+5.5+6.5+7.5+8.5+9.5=
