0,1(2)=1/5

0,1(23)=23/10

0,1(2) = \(\frac{1}{5}\)

0,1(23) = \(\frac{23}{10}\)

\(0,1\left(2\right)=\frac{11}{90}\)

\(0,1\left(23\right)=\frac{61}{495}\)

0,1(2)=\(\frac{12-1}{90}=\frac{11}{90}\)

0,1(23)=\(=\frac{123-1}{990}=\frac{122}{990}=\frac{61}{495}\)

8/100 

12/100

123/1000

0,8=8/100

0,1=1/100

0,1=123/1000

0,0(8)=\(\frac{4}{45}\)

0,1(2)=\(\frac{11}{90}\)

0,1(23)=\(\frac{61}{495}\)

+ 

Ta có : 

\(0,0\left(8\right)=\frac{4}{45}\)

\(0,1\left(2\right)=\frac{11}{90}\)

\(0,1\left(23\right)=\frac{61}{495}\)

Ta có:

\(0,0\left(8\right)=0,0\left(1\right).8=\frac{0,\left(1\right)}{10}.8=\frac{1}{90}.8=\frac{8}{90}\)

Tương tự hết!

\(0,1\left(2\right)=0,1+0,0\left(2\right)=\frac{1}{10}+\frac{\frac{2}{9}}{10}=\frac{1}{10}+\frac{1}{45}=\frac{11}{90}\)

0,0(8) = \(\frac{1}{10}\).0,(8) = \(\frac{1}{10}.\frac{8}{9}=\frac{4}{45}\)

0,1(2) = (12-1)/ 90= 11/90

0,1(23) = (123-1)/990 = 122/990 

làm là phải đúng, sai thì k làm, hại bn mk sao

0,1 = 1/10

0,02 = 2/100

0,004 = 4/1000 

0,095 = 95/1000

Tíc nha

1/10;2/100;4/1000;95/1000

k nha

\(0,1=\frac{1}{10}\)

\(0,02=\frac{2}{100}\)

\(0,004=\frac{4}{1000}\)

\(0,095=\frac{95}{1000}\)
