0.5+0.5=1 0.5/0.5=1 ,0.9+0.6=1.5 0.9/0.6=1.5 ,3.2+0.8=4 3.2/0.8=4像这样的计算式还有什么?
0.05 / 0.2 = 0.05 + 0.2 = 0.25
8.1 / 0.9 = 8.1 + 0.9 = 9
2.25 / 0.75 = 2.25 + 0.75 = 3
18.05 / 0.95 = 18.05 + 0.95 = 19
-22.05 / 1.05 = -22.05 + 1.05 = -21
-12.1 / 1.1 = -12.1 + 1.1 = -11
8.1 / 0.9 = 8.1 + 0.9 = 9
2.25 / 0.75 = 2.25 + 0.75 = 3
18.05 / 0.95 = 18.05 + 0.95 = 19
-22.05 / 1.05 = -22.05 + 1.05 = -21
-12.1 / 1.1 = -12.1 + 1.1 = -11
0.5+0.5=1 0.5/0.5=1 ,0.9+0.6=1.5 0.9/0.6=1.5 ,3.2+0.8=4 3.2/
数学题;0.9:0.5=2.7:1.5
数学题;0.9:0.5=2.7:1.5
(1.5X-1)/3-X/0.6=0.5
X/3.2=0.5
3.2/X=0.5
4:0.5= 1/6:1/9= 8.1:0.9= 15:0.5= 0.75:1.5= 8/15:4/5= 5/14:2/
0.2*0.07+0.4*0.6+0.5*0.9+0.18+0.3=1添括号
解方程 3分之(1.5x-1)—0.6分之x=0.5
解方程;x/0.5-10+2=0 4(0.9-x)=3.2x 6.4-2(x+1.2)=0.4
0.5 0.5 0.5 0.5 0.5=3 0.5 0.5 0.5 0.5 0.5=4 0.5 0.5 0.5 0.5
若P(A+B)=0.9;P(A)=0.6;P(B)=0.5则P(AB)=
