ayuda x favor gracias​

Answer 1

Respuesta:

$a) \frac{5}{8} + \frac{3}{4} + x = \frac{9}{4} \\ x = \frac{9}{4} - \frac{5}{8} - \frac{3}{4} \\ x = \frac{18}{8} - \frac{5}{8} - \frac{6}{8} \\ x = \frac{7}{8}$

$b) \frac{1}{6} + \frac{2}{3} + x = 2 \\ x = 2 - \frac{1}{6} - \frac{2}{3} \\ x = \frac{12}{6} - \frac{1}{6} - \frac{4}{6} \\ x = \frac{7}{6}$

$c) \frac{10}{5} + \frac{5}{10} + x = 4 \\ x = 4 - \frac{10}{5} - \frac{5}{10} \\ x = \frac{40}{10} - \frac{20}{10} - \frac{5}{10} \\ x = \frac{15}{10} = \frac{3}{2}$

$d) \frac{4}{5} + \frac{2}{2} = \frac{8}{10} + \frac{10}{10} = \frac{18}{10} = \frac{9}{5}$

$e) \frac{7}{8} + \frac{3}{4} = \frac{7}{8} + \frac{6}{8} = \frac{13}{8}$

$f) \frac{6}{6} + \frac{2}{3} = \frac{6}{6} + \frac{4}{6} = \frac{10}{6} = \frac{5}{3}$
