### Instruction: If $a+\frac {a} {3}=\frac {8} {3}$, what is the value of $a$?### Response: I want to solve for $a$, so I need to get rid of the fraction $\frac {a} {3}$ on the left side of the equation.
I can do this by multiplying both sides of the equation by $3$, which will clear the denominator.
This gives me $3a+a=8$, or $4a=8$.
To isolate $a$, I can divide both sides by $4$.
This gives me $a=2$.
