4-52.

Resuelve cada ecuación en seguida para $x$ . Luego revisa tus soluciones.

$\frac { x } { 8 } = \frac { 3 } { 4 }$
Pista (a):
Multiplica ambos lados por 8.
$8 \cdot \frac{x}{8}=\frac{3}{4}\cdot 8$
$x=\frac{24}{4}$
Respuesta (a):
$x = 6$

$\frac { 2 } { 5 } = \frac { x } { 40 }$
Pista (b):
Use the same method outlined in part (a).

$\frac { 1 } { 8 } = \frac { x } { 12 }$
Pista (c):
Use the same method as part (a). Multiply both sides by $12$ .
Respuesta (c):
$x = 1.5$

$\frac { x } { 10 } = \frac { 12 } { 15 }$
Pista (d):
Use the methods shown in parts (a) and (c) to solve.
