Solve this :
(0.56% of 225) × (3.25% of 430) = ?

$$\left( {0.56\% \,\,{\text{of}}\,\,255} \right) \times $$   $$\left( {3.25\% \,\,{\text{of}}\,\,430} \right)$$
$$ = \left( {\frac{{56}}{{100}} \times \frac{1}{{100}} \times 225} \right) \times $$     $$\left( {\frac{{325}}{{100}} \times \frac{1}{{100}} \times 430} \right)$$
$$\eqalign{ & = \left( {\frac{{126}}{{100}} \times \frac{{13975}}{{1000}}} \right) \cr & = 1.26 \times 13.975 \cr & = 17.6085 \cr} $$
