Question

Hola alguien me puede ayudar es para pasado mañana

Answer 1

Explicación paso a paso:

para encontrar fracciones equivalentes, podemos AMPLIFICAR las fracciones multiplicando por fracciones equivalentes a la unidad. Por ejemplo:

$\frac{1}{2} \times \frac{2}{2} = \frac{2}{4} \\ \\ \frac{1}{2} \times \frac{3}{3} = \frac{3}{6} \\ \\ \frac{1}{2} = \frac{2}{4} = \frac{3}{6}$

Solución:

$\frac{3}{5} = (\times \frac{2}{2} = \frac{6}{10} ) = ( \times \frac{3}{3} = \frac{9}{15}) = ( \times \frac{5}{5} = \frac{15}{25} ) = ( \times \frac{7}{7} = \frac{21}{35} ) = ( \times \frac{11}{11} = \frac{33}{55}) \\ \\ \frac{6}{7} = (\times \frac{2}{2} = \frac{12}{14} ) = ( \times \frac{3}{3} = \frac{18}{21}) = ( \times \frac{5}{5} = \frac{30}{35} ) = ( \times \frac{7}{7} = \frac{42}{49} ) = ( \times \frac{11}{11} = \frac{66}{77}) \\ \\ \frac{10}{3} = (\times \frac{2}{2} = \frac{20}{6} ) = ( \times \frac{3}{3} = \frac{30}{9}) = ( \times \frac{5}{5} = \frac{50}{15} ) = ( \times \frac{7}{7} = \frac{70}{21} ) = ( \times \frac{11}{11} = \frac{110}{33}) \\ \\ \frac{17}{13} = (\times \frac{2}{2} = \frac{34}{26} ) = ( \times \frac{3}{3} = \frac{51}{39}) = ( \times \frac{5}{5} = \frac{85}{65} ) = ( \times \frac{7}{7} = \frac{119}{91} ) = ( \times \frac{11}{11} = \frac{187}{143})$
