Let the number of sugar crystals in 5 kg of sugar be x.
The given information in the form of a table is as follows.

Amount of sugar (in kg)	2	5
Number of crystals	9 × 10⁶	x

The amount of sugar and the number of crystals it contains are directly proportional to each other. Therefore, we obtain
{tex}\frac{2}{{9 \times {{10}^6}}} = \frac{5}{x}{/tex}
{tex}x = \frac{{5 \times 9 \times {{10}^6}}}{2} = 2.25 \times {10^7}{/tex}
Hence, the number of sugar crystals is 2.25 × 10⁷.
