Short Answer

Expert verified

The solution is $a = 11$ .

Step by step solution

Step 1. Given

The given proportion is $\frac{a}{12} = \frac{33}{36}$ .

Step 2. To determine

We have to solve the proportion using equivalent ratios.

Step 3. Calculation

Solve the given proportion.

$\begin{matrix} \frac{a}{12} = \frac{33}{36} \\ \frac{a}{12 \times 3} = \frac{33}{36} [comparedenominators] \\ \frac{a \times 3}{36} = \frac{33}{36} [find a] \\ 3 a = 33 \\ 3 a \div 3 = 33 \div 3 [divideeachby3] \\ a = 11 \end{matrix}$

So, the solution is $a = 11$ .
