Respuesta:
[tex]\frac{28}{15}[/tex] y [tex]\frac{49}{12}[/tex]
Explicación paso a paso:
2.- [tex]\frac{6}{5}[/tex] - [tex]\frac{2}{3}[/tex]
[tex]\frac{6(3) + 5(2)}{5(3)}[/tex] = [tex]\frac{18 + 10}{15}[/tex] = [tex]\frac{28}{15}[/tex]
3.- [tex]\frac{8}{2}[/tex] - [tex]\frac{7}{6}[/tex] + [tex]\frac{5}{4}[/tex]
[tex]\frac{8(6) - 2(7)}{2(6)}[/tex] + [tex]\frac{5}{4}[/tex] = [tex]\frac{48 - 14}{12}[/tex] + [tex]\frac{5}{4}[/tex] = [tex]\frac{34}{12}[/tex] + [tex]\frac{5}{4}[/tex] = [tex]\frac{17}{6}[/tex] + [tex]\frac{5}{4}[/tex] = [tex]\frac{17(4) + 6(5)}{6(4)}[/tex] = [tex]\frac{68 + 30}{24}[/tex] = [tex]\frac{98}{24}[/tex] = [tex]\frac{49}{12}[/tex]

Verified answer
primero simplificamos4/1-7/6+5/4
después escribimos cada fracción sobre el MCD 12 y nos da
48-14+15/12
calculamos la suma y resta y nos da
RESPUESTA: 49/12
ponme corona pls me demoré
