8、5X(10十0、1)

36*10.1=36*(10+0.1)=36*10+36*0.1=360+3.6=363.6

9.6x10.1=9.6x(10+0.1)=9.6x10+9.6x0.1=96+0.96=96.96

5.2X10.1 =5.2*(10+0.1) =5.2*10+5.2*0.1 =52+0.52 =52.52

9.9*10.1=9.9*(10+0.1)=9.9*10+9.9*0.1=99+0.99=99.99

6.3x10.1=6.3*(10+0.1)=6.3*10+6.3*0.1=63+0.63=63.63

53x10.1=53x(10+0.1)=53x10+53x0.1=530+5.3=535.3

65x10.1=65*10+65*0.1=650+6.5=656.5

17X10.1=17x(10+0.1)=17x10+17x0.1=17+1.7=18.7

4.8*10.1=4.8*(10+0.1)=4.8*10+0.1*4.8=48+0.48=48.48
