Write the following as an equation, using x for the unknown number. Then solve.
-Three-fourths of a number is $\frac { 1 } { 2 }$ . Find the number in lowest terms.

A) $\frac { 3 } { 4 } x = \frac { 1 } { 2 } ; \frac { 4 } { 6 }$
B) $\frac { 3 } { 4 } x = \frac { 1 } { 2 } ; \frac { 3 } { 8 }$
C) $\frac { 3 } { 4 } + x = \frac { 1 } { 2 } ; - \frac { 1 } { 2 }$
D) $\frac { 3 } { 4 } x = \frac { 1 } { 2 } ; \frac { 2 } { 3 }$
