Answer 1

•Nī haõ 你好

✔️Solucion:

$a) \: \frac{2}{3} + \frac{5}{6} = \frac{4 + 5}{6} = \frac{9}{6} = \frac{3}{2}$

$b) \: \frac{5}{4} + \frac{7}{8} = \frac{10 + 7}{8} = \frac{17}{8}$

$c) \: \frac{7}{5} + \frac{8}{15} = \frac{21 + 8}{15} = \frac{29}{15}$

$d) \: \frac{1}{4} + \frac{3}{7} = \frac{7 + 2}{28} = \frac{19}{28}$

$e) \: \frac{5}{6} + \frac{3}{5} = \frac{25 + 18}{30} = \frac{43}{30}$

TEMA:SUMA DE FRACCIONES HETEROGÈNEAS

——————————

sumamos los siguientes fracciones heterogeneas de la siguiente manera:

$\frac{2}{3} + \frac{5}{6} = \frac{4 + 5}{6} = \frac{9}{6} \\ \frac{5}{4} + \frac{7}{8} = \frac{10 + 7}{8} = \frac{17}{8} \\ \frac{7}{5} + \frac{8}{15} = \frac{27 + 8}{15} = \frac{29}{15} \\ \frac{1}{4} + \frac{3}{7} = \frac{7 + 12}{28} = \frac{19}{28} \\ \frac{5}{6} + \frac{3}{5} = \frac{25 + 18}{30} = \frac{43}{30}$
