Làm ơn 

\(\frac{12}{23}\)???

TL :

12,23 = 1 223/ 100

13,123=  13 123 / 1 000

324,701 = 324 701 / 1 000

a) \(2,6=2+0,6=2\dfrac{3}{5}=\dfrac{13}{5}\)

b) \(3,57=3+0,57=3\dfrac{57}{100}=\dfrac{357}{100}\)

c) \(67,01=67+0,01=67\dfrac{1}{100}=\dfrac{6701}{100}\)

d) \(9,505=9+0,505=9\dfrac{101}{200}=\dfrac{1901}{200}\)

8 , 06   = 8 6 100   ;               72 , 308   =   72 308 1000   ;             20 , 006 = 20 6 1000

a,2\(\frac{6}{10}=\frac{26}{10}\)

b,\(3\frac{57}{100}=\frac{357}{100}\)

c,\(67\frac{1}{100}=\frac{6701}{100}\)

d,\(9\frac{505}{1000}=\frac{9505}{1000}\)

có đúng không ?đúng thì k nha các bạn

a,\(2\frac{6}{10}\)= \(\frac{26}{10}\)   

b, \(3\frac{57}{100}\)= \(\frac{357}{100}\)      

c, \(67\frac{1}{100}\) =  \(\frac{6701}{100}\)      

d, \(9\frac{505}{1000}\) = \(\frac{9505}{1000}\)

a)2,6=2/6/10=26/10

b)3,57=3/57/100=357/100

c)67,01=67/1/100=6701/100

d)9,505=9/505/1000=9505/1000

3 , 5   =   3 5 10 ;               7 , 9 = 7 9 10 ;             12 , 35 = 12 35 100

\(a.72,308=72\frac{308}{1000}\)

\(b.20,006=20\frac{6}{1000}\)

\(72,308=72\frac{308}{100}\)

\(20,006=20\frac{6}{1000}\)
