\(\frac{57}{133}=\frac{57\div19}{133\div19}=\frac{3}{7}\)
\(\frac{189}{210}=\frac{189\div21}{210\div21}=\frac{9}{10}\)
\(\frac{7676}{8484}=\frac{7676\div404}{8484\div404}=\frac{19}{21}\)
lần lượt = 3/7 ; 9/10 ; 19/21
Ta có :
\(\frac{57}{133}=\frac{57:19}{133:19}=\frac{3}{7}\)
\(\frac{189}{210}=\frac{189:21}{210:21}=\frac{9}{10}\)
\(\frac{7676}{8484}=\frac{7676:404}{8484:404}=\frac{19}{21}\)
\(\frac{57}{133}=\frac{3}{7}\)
\(\frac{189}{210}=\frac{9}{10}\)
\(\frac{7676}{8484}=\frac{19}{21}\)
57/133 = 3/7
189/210 = 9/10
7676/8484= 19/21
