(i) 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 x 106 x

The amount of sugar and the number of crystals it contains are directly proportional to each other. Therefore, we obtain

Hence, the number of sugar crystals is 2.25 × 107.

(ii) Let the number of sugar crystals in 1.2 kg of sugar be y. The given information in the form of a table is as follows.

Amount of sugar (in kg) 2 1.2
Number of crystals 9 x106 y

Hence, the number of sugar crystals is 5.4 x 106
