Ấy chết sai !

\(\frac{272727}{323232}=\frac{272727\div10101}{323232\div10101}=\frac{27}{32}\)

Đáp số : \(\frac{27}{32}\)

Ta có: \(\frac{272727}{323232}=\frac{272727:10101}{323232:10101}=\frac{27}{32}\)

\(\frac{272727}{323232}=\frac{272727:101}{323232:101}=\frac{27}{32}\)

\(\dfrac{323232}{242424}=\dfrac{323232:80808}{242424:80808}=\dfrac{4}{3}\)

\(\dfrac{323232}{242424}=\dfrac{323232:80808}{242424:80808}=\dfrac{4}{3}\)

             Giải

\(\frac{222222}{323232}=\frac{222222:20202}{323232:20202}=\frac{11}{16}\)

Vậy rút gọn phân số \(\frac{222222}{323232}\)ta được phân số

là \(\frac{11}{16}\)

ta được phân số:\(\frac{11}{16}\)

\(\frac{222222}{323232}=\frac{22}{32}=\frac{11}{16}\)

\(\frac{3}{8}\)

Ta có :

\(\frac{272727}{727272}=\frac{272727\div90909}{727272\div90909}=\frac{3}{8}\)

272727/727272=272727/727272 :9=333/888

\(\frac{323232}{424242}=\frac{32\cdot10101}{42\cdot10101}=\frac{32}{42}=\frac{16}{21}\)

16/21 nha!

\(\frac{323232:20202}{424242:20202}=\frac{16}{21}\)

        ~ học tốt ~

30303/474747=(10101x3)/(10101x47)=3/47

mấy câu sau tương tự nha e tách 10101 ra

Trả lời: 

\(\frac{303030}{474747}=\frac{303030:10101}{474747:10101}=\frac{30}{47}\)                                          \(\frac{212121}{353535}=\frac{212121:10101}{353535:10101}=\frac{21}{35}\)                       

 \(\frac{676767}{656565}=\frac{676767:10101}{656565:10101}=\frac{67}{65}\)                                      \(\frac{323232}{989898}=\frac{323232:10101}{989898:10101}=\frac{32}{98}\)

lạy bạn. nó chưa phải phân số tối giản + sai câu đầu

Rút gọn phân số:

a)1717/2323 = 17/23

b)123123/123123 = 1

c)262626/272727 = 26/27

d)42424242/43434343 = 42/43

A) 17/23

B) 123/123

C) 26/27

D) 42/43

K mk nhé 

a. \(\frac{1717}{2323}\)= \(\frac{1717:101}{2323:101}\)= \(\frac{17}{23}\)

b. \(\frac{123123}{234234}\)= \(\frac{123123:1001}{234234:1001}\)= \(\frac{123}{234}\)

( Những câu còn lại tương tự như trên )

a. \(\dfrac{656565}{272727}=\dfrac{65}{27}\)

b. \(\dfrac{2}{7}\left(\dfrac{3}{4}+\dfrac{9}{4}\right)=\dfrac{6}{7}\)

Ta có:

\(\begin{array}{l}\frac{{24}}{{108}} = \frac{{24:12}}{{108:12}} = \frac{2}{9};\\\frac{{80}}{{32}} = \frac{{80:16}}{{32:16}} = \frac{5}{2}\end{array}\)
