\frac{a^{2}+6}{6\left(a+\frac{6}{a}\right)}
Express \frac{\frac{a^{2}+6}{6}}{a+\frac{6}{a}} as a single fraction.
\frac{a^{2}+6}{6\left(\frac{aa}{a}+\frac{6}{a}\right)}
To add or subtract expressions, expand them to make their denominators the same. Multiply a times \frac{a}{a}.
\frac{a^{2}+6}{6\times \frac{aa+6}{a}}
Since \frac{aa}{a} and \frac{6}{a} have the same denominator, add them by adding their numerators.
\frac{a^{2}+6}{6\times \frac{a^{2}+6}{a}}
Do the multiplications in aa+6.
\frac{a^{2}+6}{\frac{6\left(a^{2}+6\right)}{a}}
Express 6\times \frac{a^{2}+6}{a} as a single fraction.
\frac{\left(a^{2}+6\right)a}{6\left(a^{2}+6\right)}
Divide a^{2}+6 by \frac{6\left(a^{2}+6\right)}{a} by multiplying a^{2}+6 by the reciprocal of \frac{6\left(a^{2}+6\right)}{a}.
\frac{a}{6}
Cancel out a^{2}+6 in both numerator and denominator.
\frac{a^{2}+6}{6\left(a+\frac{6}{a}\right)}
Express \frac{\frac{a^{2}+6}{6}}{a+\frac{6}{a}} as a single fraction.
\frac{a^{2}+6}{6\left(\frac{aa}{a}+\frac{6}{a}\right)}
To add or subtract expressions, expand them to make their denominators the same. Multiply a times \frac{a}{a}.
\frac{a^{2}+6}{6\times \frac{aa+6}{a}}
Since \frac{aa}{a} and \frac{6}{a} have the same denominator, add them by adding their numerators.
\frac{a^{2}+6}{6\times \frac{a^{2}+6}{a}}
Do the multiplications in aa+6.
\frac{a^{2}+6}{\frac{6\left(a^{2}+6\right)}{a}}
Express 6\times \frac{a^{2}+6}{a} as a single fraction.
\frac{\left(a^{2}+6\right)a}{6\left(a^{2}+6\right)}
Divide a^{2}+6 by \frac{6\left(a^{2}+6\right)}{a} by multiplying a^{2}+6 by the reciprocal of \frac{6\left(a^{2}+6\right)}{a}.
\frac{a}{6}
