(15)/(a)=(3)/(2)

To solve this proportion, we will use cross products

This means we multiply a by 3 and equate it by 15 times 2


\begin{gathered} a*3=15*2 \\ 3a=30 \end{gathered}

Now to find the value of a, we will divide both sides by 3


\begin{gathered} (3a)/(3)=(30)/(3) \\ a=10 \end{gathered}

The value of a is 10
