Question

me pueden ayudar son fracciones equivalentes ​

Answer 1

Respuesta:

$\frac{1}{14} + \frac{15}{47} + \frac{2}{7} = \frac{9 +15 + 12 }{42} = \frac{36}{42} = \frac{6}{7} \\ \\ \frac{22}{52} + \frac{11}{13} + \frac{19}{26} = \frac{22 + 44 + 38}{52} = \frac{104}{52} = 2 \\ \\ \frac{6}{30} + \frac{4}{15} + \frac{7}{3} + \frac{1}{2} + \frac{1}{6} + \frac{2}{5} = \frac{6 + 8 + 70 + 15 + 5 + 12}{30} = \frac{116}{30} = \frac{58}{15} \\ \\ a) \: \frac{21}{27} - \frac{1}{3} = \frac{21 - 9}{27} = \frac{12}{27} = \frac{4}{9} \\ \\ b) \: \frac{18}{20} - \frac{1}{2} - \frac{1}{5} = \frac{18 - 10 - 4}{20} = \frac{4}{20} = \frac{1}{5} \\ \\c) \: </p><p> \frac{1}{4} + \frac{6}{12} - \frac{2}{3} = \frac{3 + 6- 8}{12} = \frac{1}{12} \\ \\ d) \: \frac{4}{5} - \frac{4}{15} - \frac{1}{3} = \frac{12 - 4 - 5}{15} = \frac{3}{15} = \frac{1}{5} \\ \\ e) \: \frac{1}{8} + \frac{3}{4} - \frac{5}{32} = \frac{4 + 24 - 5}{32} = \frac{23}{32}$
