\(\frac{121212+12121212-1212}{363636-36363636-3636}=\frac{12\left(111111+11111111-1111\right)}{36\left(111111+11111111-1111\right)}=\frac{12}{36}=\frac{1}{3}\)

1/3 nha

\(\frac{1}{3}\)

chúc ban hk tốt!!(k cho tui nhé)

= 1/3 nha bạn 

ai k mình k lại

1/3 nha ban ghet con trai nen cu cho co gai nha 

rút gọn phân số :

121212/363636 = 3

121212/363636 

rút gọn nhanh nhất là :

121212 : 121212 = 1

363636 : 121212 = 3

Vậy phân số tối giản là 1/3

121212/363636 = 12/36 = 4/9

Ai làm nhanh nhất được tích nha bạn

Ta có: \(\frac{121212}{363636}=\frac{121212\div121212}{363636\div121212}=\frac{1}{3}\)

\(\frac{121212+12121212-1212}{363636+36363636-3636}\)

\(=\frac{12.10101+12.1010101-12.101}{36.10101+36.1010101-36.101}\)

\(=\frac{12\left(10101+1010101-101\right)}{36\left(10101+1010101-101\right)}\)

\(=\frac{12}{12.3}\)

\(=\frac{1}{3}\)

Ta có: \(\frac{121212+12121212-1212}{363636+36363636-3636}\)

           =\(\frac{12\times\left(10101+1010101-101\right)}{36\times\left(10101+1010101-101\right)}\)

           =\(\frac{12}{36}\)

           =\(\frac{1}{3}\)

\(\frac{121212+12121212-1212}{363636+36363636-3636}\)

\(=\frac{121212+12121212-1212}{3\times121212+3\times12121212-3\times1212}\)

\(=\frac{121212+12121212-1212}{3\times\left(121212+12121212-1212\right)}\)

\(=\frac{1}{3}\)

_Chúc bạn học tốt_

\(=\dfrac{1}{3}\)

\(\dfrac{121212}{363636}=\dfrac{121212\div121212}{363636\div121212}=\dfrac{1}{3}\)

\(\dfrac{121212}{363636}=\dfrac{121212\div10101}{363636\div10101}=\dfrac{12}{36}=\dfrac{1}{3}\)

4/3

A = 1/3 + 2/3 + 1/3

A = 1 + 1/3

A = 4/3

1/3+2/3+1/3

=4/3

121212/363636 được rút gọn thành 1/3

121212/363636=1x121212/3x121212

                      =1/3

\(\frac{121212}{363636}\) = \(\frac{12}{36}\) = \(\frac{1}{3}\)

Đúng thì k nha !

\(A=\frac{121212}{363636}+\frac{1212}{3636}\)

\(=\frac{1}{3}+\frac{1}{3}=\frac{2}{3}\)

#)Giải :

\(\frac{121212}{363636}=\frac{121212:10101}{363636:10101}=\frac{12}{36}=\frac{1}{3}\)

\(\frac{1212}{3636}=\frac{1212:101}{3636:101}=\frac{12}{36}=\frac{1}{3}\)

\(\Rightarrow A=\frac{1}{3}+\frac{1}{3}=\frac{2}{3}\)
