\(\frac{38}{57}=\frac{2}{3}\)

nha bn 

chúc bn học giỏi

Cảm ơn bạn nhé Linh Nguyễn

giup to cau nay

38/57 = 2/3 ( Bn chia cho 19 nha )

Mk đầu tiên

Ta có: 38/57 = 38:19/57:19 = 2/3

\(\dfrac{26}{39}=\dfrac{26:13}{39:13}=\dfrac{2}{3}\)
\(\dfrac{38}{57}=\dfrac{38:19}{57:19}=\dfrac{2}{3}\)

\(\dfrac{26}{39}=\dfrac{26:13}{39:13}=\dfrac{2}{3}\)

\(\dfrac{38}{57}=\dfrac{38:19}{57:19}=\dfrac{2}{3}\)

`26/39=(26:13)/(39:13)=2/3`

`38/57=(38:19)/(57:19)=2/3`

Rút gọn phân số: \(\frac{38}{57}\)

\(\frac{38}{57}=\frac{38:19}{57:19}=\frac{2}{3}\)

\(\frac{2}{3}\)là phân số tối giản

38/57

=38:19/ 57:19

=2/3

Đáp số:2/3

\(\frac{38}{57}=\frac{38:19}{57:19}=\frac{2}{3}\)

\(\frac{57}{133}=\frac{57\div19}{133\div19}=\frac{3}{7}\)

\(\frac{189}{210}=\frac{189\div21}{210\div21}=\frac{9}{10}\)

\(\frac{7676}{8484}=\frac{7676\div404}{8484\div404}=\frac{19}{21}\)

lần lượt = 3/7 ; 9/10 ; 19/21

Ta có :

\(\frac{57}{133}=\frac{57:19}{133:19}=\frac{3}{7}\)

\(\frac{189}{210}=\frac{189:21}{210:21}=\frac{9}{10}\)

\(\frac{7676}{8484}=\frac{7676:404}{8484:404}=\frac{19}{21}\)

27/81=1/3

57/76=3/4

35/84=5/12

27/81=1/3

57/76=3/4

35/84=5/12

2/3 bạn nhé

2 phần 3 nha bạn

2 phần 3 nha

\(\frac{19}{57}=\frac{19:19}{57:19}=\frac{1}{3}\)

\(\frac{19}{57}\) = \(\frac{1}{3}\)

rút gọn cho 19
