Answer 1

*是乘号 /是除号
0.3*2.5*0.4
50*0.13*0.2
0.8*630*0.125
0.78*101
1.5*102
9.8*25
1.2*2.5+0.8*2.5
1.25*0.7*0.8
0.038*5*2.1
3.8+4.5+6.2
93/0.31/3
3.25－0.84-0.16
88*0.25*4
2.8*3.6+1.4*2.8
63*10.1
（3.2+0.128）/0.8
9.83*1.5+6.17*1.5
10.1*87
312*4+188*4
0.135*500*0.2
7χ－2×9＝80
6x－4x＝20.2
（χ+12）÷4＝4.5
6x－0.4×6 = 9.6
118－2×( 4.1 + X ) = 55
4x ＋80 = 160
9.6÷X = 0.8
4.8－X = 3×( X ＋ 6 )
4.3X－1.5 + 3.2X = 4.5
0.4x+6.3=10.5
0.5x-0.4x=10
x+50=200/2
3X+5X=48
14X-8X=12
6*5+2X=44
20X-50=50
28+6X=88
32-22X=10
24-3X=3
10X*（5+1）=60,10,1.5+X=5.1
0.03X×5=35
5.55X÷=2.2,1,
