Respuesta:
a) solución
(multiplicamos 6 x 8 para obtener 48)
[tex] \frac{48 + 5}{8} + \frac{2 \times 4 + 3}{4} [/tex]
[tex] \frac{53}{8} + \frac{8 + 3}{4} [/tex]
[tex] \frac{53}{8} + \frac{11}{4} [/tex]
sacamos MCM de 11 y igualamos denominadores
[tex] \frac{53}{8} + \frac{22}{8} [/tex]
[tex] \frac{53 + 22}{8} [/tex]
respuesta:
[tex] \frac{75}{8} [/tex]
b) solución
(multiplicamos 8 x 4 para obtener 32)
[tex] \frac{32 + 3}{4} - \frac{5 \times 3 + 2}{3} [/tex]
[tex] \frac{35}{4} - \frac{15 + 2}{3} [/tex]
[tex] \frac{35}{4} - \frac{17}{3} [/tex]
[tex] \frac{105}{12} - \frac{68}{12} [/tex]
[tex] \frac{105 - 68}{12} [/tex]
[tex] \frac{37}{12} [/tex]
c)
(multiplicamos 8 x 10 para obtener 80)
[tex] \frac{80 + 3}{10} - \frac{3 \times 5 + 4}{5} [/tex]
[tex] \frac{83}{10} - \frac{15 + 4}{5} [/tex]
[tex] \frac{83}{10} - \frac{19}{5} [/tex]
[tex] \frac{83}{10} - \frac{38}{10} [/tex]
[tex] \frac{83 - 38}{10} [/tex]
[tex] \frac{45}{10} [/tex]
simplificamos y la respuesta sería :
[tex] \frac{9}{2} [/tex]
espero averte ayudado (◍•ᴗ•◍)✧*。
