Simplify the numerical expression. Remember that fractions are not considered simplified unless they are reduced. $$\frac { 4 } { 5 } + \frac { 1 } { 7 }$$
A) $\frac { 35 } { 33 }$
B) $\frac { 1 } { 7 }$
C) $\frac { 5 } { 12 }$
D) $\frac { 33 } { 35 }$
E) $\frac { 5 } { 28 }$

To simplify the expression, find a common denominator, which is 35. Then, $\frac{4}{5} = \frac{4*7}{5*7} = \frac{28}{35}$ and $\frac{1}{7} = \frac{1*5}{7*5} = \frac{5}{35}$. Adding these fractions gives $\frac{28}{35} + \frac{5}{35} = \frac{33}{35}$.
