The denominator can be simplified with the distributive property.
[tex] \frac{2q}{16(q + r)} [/tex]
[tex] \frac{2q}{16q + 16r} [/tex]
Then simplify the fraction by prime factorizing each term in the fraction and cancel out common factors.
[tex] \frac{2q}{16q + 16r} = \frac{(2)(q)}{(2)(2)(2)(2)(q) + (2)(2)(2)(2)(r)} = \\ \\
\frac{1}{(2)(2)(2) + (2)(2)(2)(2)(r)} = \frac{1}{8 + 16r} [/tex]
So, that is the simplified form.
