Problem
Solve for a in the proportion 1/9 = a/6.
Step-by-step solution
To solve for 'a', cross-multiply the equation $\frac{1}{9} = \frac{a}{6}$. This gives $1 \times 6 = 9 \times a$, which simplifies to $6 = 9a$. Dividing both sides by 9 yields $a = \frac{6}{9}$, which simplifies to $a = \frac{2}{3}$.
Answer
$a = \frac{2}{3}$
