If $\frac { 1 } { 4 }$ of $x$ is $16$, what is $\frac { 3 } { 4 }$ of $x$? Justify your answer in more than one way.

Write out equations to represent these phrases.
$\text{If }\frac{1}{4}x = 16,\text{ find } \frac{3}{4}x.$

Solve for $x$ in the first equation: $x = 64$

Substitute $64$ for $x$ in the second equation.
$\frac{3}{4} (64)$
