104*2.5 1.25*(4-0.8) 4.2*0.5-1.6*0.52 12.5*32*0.25 0.48*99+0.48 63*10.1 列竖式今天要
104*2.5
=(100+4)×2.5
=100×2.5+4×2.5
=250+10
=260
1.25*(4-0.8)
=1.25×4-1.25×0.8
=5-1
=4
4.2*0.5-1.6*0.52
=2.1-0.832
=1.268
12.5*32*0.25
=12.5×8×4×0.25
=100×1
=100
0.48*99+0.48
=0.48×(99+1)
=0.48×100
=48
63*10.1
=63×(10+0.1)
=63×10+63×0.1
=630+6.3
=636.3
=(100+4)×2.5
=100×2.5+4×2.5
=250+10
=260
1.25*(4-0.8)
=1.25×4-1.25×0.8
=5-1
=4
4.2*0.5-1.6*0.52
=2.1-0.832
=1.268
12.5*32*0.25
=12.5×8×4×0.25
=100×1
=100
0.48*99+0.48
=0.48×(99+1)
=0.48×100
=48
63*10.1
=63×(10+0.1)
=63×10+63×0.1
=630+6.3
=636.3
104*2.5 1.25*(4-0.8) 4.2*0.5-1.6*0.52 12.5*32*0.25 0.48*99+0
简便计算 6.2×1.02 1.25 ×99 12.5×32×2.5 4.12-1.78-1.22 4.2÷0.7÷6
9.9×2.3 12.5×0.8×4×0.5 2.5×0.32×1.25 5.3×10.1 简便计算,要有列式.
1.25*2.3*0.8 2.4*1.8*7.6*1.8 3.2*0.25*4 32*0.125*2.5 求简算,
要简便方法计算.0.25*0.62*4= (2.8+0.5)*2= 104*2.5= 48*1.25=
(12.5+1.25+0.25)*0.8怎么简便
198×0.51 1.25×2.5 0.8×72.4×12.5
0.5x-4×0.25=1.25 32:X=3/5:4/5 (1.5x+2)×0.5=1.6
12.5×4-0.8×0.25 求巧算
1.25×0.52×0.8简算
99*7.56+7.56 2.5*3.2 *1.25 【0.125+1.25+12.5】*8
0.02*38.7*50 39.6*99 1.25*(8+0.8) 1.25*0.2*32 4.57*3.1-2.1*4
