FRACCIONES EQUIVALENTES

$\frac{5}{4} = \frac{10}{8} = \frac{15}{12}$

$-\frac{2}{3} = -\frac{4}{6} = -\frac{6}{9}$

$\frac{7}{5} = \frac{14}{10} = \frac{21}{15}$

$\frac{1}{20} = \frac{2}{40} =\frac{3}{60}$

$\frac{19}{11} = \frac{38}{22}= \frac{57}{33}$

$\frac{17}{30}= \frac{34}{60} =\frac{51}{90}$

$\frac{3}{7} = \frac{6}{14} =\frac{9}{21}$

$\frac{25}{33} = \frac{50}{66} =\frac{75}{99}$

$\frac{117}{45} = \frac{234}{90}= \frac{351}{135}$



PASAR A FRACCION

$0,51 = \frac{51}{100}$

$0,51515151..... = 0,<strong>51</strong> = \frac{51}{99} = \frac{17}{33}$

$0,36515151..... = 0,36<strong>51</strong> = \frac{3651-36}{9900} = \frac{3615}{9900} = \frac{1205}{3300} = \frac{241}{660}$
