Respuesta:
A) 4
B) 1
C) 22
D) 3
Explicación paso a paso:
A)
[tex] \frac{5}{10} = \frac{y}{8} \\ 40 = 10y \\ \frac{40}{10} = y \\ 4 = y[/tex]
B)
[tex] \frac{10}{2a} = \frac{20}{4} \\ 40 = 40a \\ \frac{40}{40} = a \\ 1 = a[/tex]
C)
[tex] \frac{4}{m} = \frac{2}{11} \\ 44 = 2m \\ \frac{44}{2} = m \\ 22 = m[/tex]
D)
[tex] \frac{3y}{2} = \frac{18}{4} \\ 12y = 36 \\ y = \frac{36}{12} \\ y = 3[/tex]
