but I don't get what the question is asking.. it says what is the reciprocal of 5 and 1/5... but how is it 5 or 1/5?

its asking what two numbers can you add together and get 5 and 1/2 or what numbers can you add together and get 5+1/2 note: 5 is the recipicle of 1/5 and vice versa

5+1/5 = 5 and 1/5 5^(1) = 1/5

\[x+\frac 1x=5~\frac 15\]\[\frac {x^2+1}x=\frac {26}5\]\[x^2+1=\left(\frac {26}5\right)x\]\[x^2\left(\frac{26}5\right)x+1=0\] \[x_{1,2}=\frac{(\frac{26}5)\pm\sqrt{(\frac{26}5)^24}}{2}\]\[\qquad=\frac{\frac{26}5\pm\sqrt{\frac{676}{25}4}}{2}\]\[\quad=\quad...\]
