Ta có : \(0,\left(1\right)=\frac{1}{9};\)\(0,0\left(1\right)=\frac{1}{90};\)\(0,00\left(1\right)=\frac{1}{900}\)nên suy ra:

\(-2,37\left(1\right)=-\left[2,37\left(1\right)\right]\)

\(=-\left[2,37+0,00\left(1\right)\right]\)

\(=-\left[2,37+\frac{1}{900}\right]\)

\(=-\left[\frac{2133}{900}+\frac{1}{900}\right]\)

\(=-\frac{2134}{900}=\frac{-1067}{450}\)

Vậy \(-2,37\left(1\right)=\frac{-1067}{450}\)

-2,37(1)= -2,37+0,00(1)

           = -2,37+100+0,(1)

           = -2,37+100+1/9

\(\frac{-1067}{450}\)

\(\frac{-1067}{450}\)nhé

-1067/450 nhé

bang 1067/450 .

\(-2,37\left(1\right)=-2,37+\left(-0,00\left(1\right)\right)=-2,37+\frac{-1}{900}=\frac{-1067}{450}\)

Ta có: \(-2,37\left(1\right)=-2,37-0,00\left(1\right)=\frac{-237}{100}-\frac{1}{100}\times0,\left(1\right)=\frac{-237}{100}-\frac{1}{100}\times\frac{1}{9}=\frac{-237}{100}-\frac{1}{900}=\frac{-1067}{450}\)

Vậy số \(-2,37\left(1\right)\) được viết dưới dạng phân số tối giản là \(\frac{-1067}{450}\).

\(\dfrac{13}{15}-\dfrac{1}{5}=\dfrac{13}{15}=\dfrac{3}{15}=\dfrac{10}{15}=\dfrac{2}{3}\)

\(\dfrac{7}{8}\times\dfrac{2}{7}=\dfrac{14}{56}=\dfrac{1}{4}\)

a. 0,35 = \(\dfrac{7}{20}\)

0,016 = \(\dfrac{2}{125}\)

-0,15 = \(\dfrac{-3}{20}\)

1,18 = \(\dfrac{59}{50}\) 

\(x:\dfrac{1}{8}=\dfrac{6}{11}\\ x=\dfrac{6}{11}\times\dfrac{1}{8}\\ x=\dfrac{3}{44}\)

3/44

x = 6/11×1/8

x = 6/88

x=3/44
