Suppose 2 kg of sugar contains `9 xx 10^6` crystals. How many sugar crystals are there in (i) 5 kg of sugar? (ii) 1.2 kg of sugar?

Explanation

To solve the problem, we will use the concept of direct proportion. The number of sugar crystals is directly proportional to the weight of sugar.

### Step-by-Step Solution:

1. **Identify the relationship**: We know that 2 kg of sugar contains \(9 \times 10^6\) crystals. This means that for every 2 kg of sugar, there are \(9 \times 10^6\) crystals.

2. **Find the number of crystals per kg**:
