2.7+2.7=63÷0.9=0.3÷1.5=10÷0.2=
0.95÷5=0×1.7=6÷5=1.8÷0.36=

解：3÷4=0.75；0.9÷3=0.3；1.5÷0.5=3；10×0.28=2.8；
20÷0.4=50；1.2÷0.6=2；0.83+0.25=1.08；1-0.08=0.92；
5χ-χ=4x；X+X=2x；8×12.5=100；0.6×1.5=0.9；
2.7+2.7=5.4；63÷0.9=70；0.3÷1.5=0.2；10÷0.2=50；
0.95÷5=0.19；0×1.7=0；6÷5=1.2；1.8÷0.36=5．
故答案依次為：0.75，0.3，3，2.8，50，2，1.08，0.92，4x，2x，100，0.9，5.4，70，0.2，50，0.19，0，1.2，5．
