0.4:x=1.2:2.12:2.4=3:x.0.4:x=1.2:2.12:2.4=3:x.0.4:x=1.2:2.12:2.4=3:x.两内项之积等于两外项之积.0.4:X=1.2:2X=0.4*2
0.4:x=1.2:2.12:2.4=3:x.
0.4:x=1.2:2.12:2.4=3:x.
0.4:x=1.2:2.12:2.4=3:x.
两内项之积等于两外项之积.
0.4:X=1.2:2
X=0.4*2/1.2
X=0.8/1.2
X=2/3
12:2.4=3:x
12x=2.4×3
x=2.4×3÷12
x=0.6
检验
左边=12:2.4=12÷2.4=5
x=0.6,右边=3÷0.6=5
等式成立
所以x=0.6是方程的解
1、x=8/15
2、x=3/5=0.6
0.4:x=1.2:2.12:2.4=3:x.
