Respuesta:
a) [tex]\frac{11}{21}[/tex]
b) [tex]\frac{11}{12}[/tex]
Explicación paso a paso:
a) [tex]\frac{1}{6}[/tex] + [tex]\frac{5}{14}[/tex]
M-C-M (6; 14)
6 - 14║2 MCM (6; 14) = 2 x 3 x 7 = 42
3 - 7 ║3 [tex]\frac{1}{6}[/tex] x 7 = [tex]\frac{7}{42}[/tex]
1 - 7 ║ 7 [tex]\frac{5}{14}[/tex] x 3 = [tex]\frac{15}{42}[/tex]
1 - 1 [tex]\frac{7}{42}[/tex] + [tex]\frac{15}{42}[/tex] = [tex]\frac{22}{42}[/tex] = [tex]\frac{11}{21}[/tex]
b) [tex]\frac{7}{12}[/tex] + [tex]\frac{5}{15}[/tex]
M-C-M (12; 15)
12 - 15║2 MCM (12; 15) = 2 x 2 x 3 x 5 = 60
6 - 15 ║2 [tex]\frac{7}{12}[/tex] x 5 = [tex]\frac{35}{60}[/tex]
3 - 15║3 [tex]\frac{5}{15}[/tex] x 4 = [tex]\frac{20}{60}[/tex]
1 - 5 ║5 [tex]\frac{35}{60}[/tex] + [tex]\frac{20}{60}[/tex] = [tex]\frac{55}{60}[/tex] ÷ 5 = [tex]\frac{11}{12}[/tex]
