8,35 = \(\frac{835}{100}\) (= \(\frac{167}{20}\))

835/100

\(\frac{835}{100}\)

3 = 3/1

4 = 4/1

\(3=\frac{3}{1}=\frac{6}{2}=\frac{9}{3}=...=\frac{3.n}{n}\)

\(4=\frac{4}{1}=\frac{8}{2}=\frac{12}{3}=...=\frac{4.n}{n}\)

3/4= 75/100=0,75 .

Nha bn ! 

ra thap phan bg 0,75

\(\frac{3}{4}=0,75\)

0,45 cho mình nhé Huyền

Ai nhanh mk k cho nguoc lai k mk  nhe !

0,45 nhé bn

600% hoặc 0.06%

tích nha !

minh biet cach giai chu khong biet tra loi 

ds:18 phan doi co 8 ban 

4 phan doi co 9 ban    

=\(\frac{13}{5}\)

3,(1) = 3+ 0,(1)

        = 3 + \(\frac{1}{9}\) = \(\frac{28}{9}\)

\(3,\left(45\right)=3+0,\left(45\right)=3+\frac{45}{99}\)

\(=3+\frac{5}{11}\)

\(=\frac{33}{11}+\frac{5}{11}=\frac{38}{11}\)
