B. 3/6-1/3
C.(7/8*1/4÷3/5)

ayuda ​

Answer 1

Respuesta:

$\frac{4}{5}+\frac{2}{7}=\frac{(7)(4)+(5)(2)}{35} = \frac{28+10}{35}=\frac{38}{35}\\\\\frac{3}{6}-\frac{1}{3}=\frac{(1)(3)-(2)(1)}{6}=\frac{3-2}{6}=\frac{1}{6} \\\\(\frac{7}{8})(\frac{1}{4}) : \frac{3}{5}) = (\frac{7}{32})(\frac{5}{3})=\frac{35}{96}$

Espero sea de ayuda!
