Give four rational numbers equivalent to: (i) `(-2)/7` (ii) `5/(-3)` (iii) `4/9`

Explanation

To find four rational numbers equivalent to the given rational numbers, we can multiply and divide each number by the same non-zero integer. Let's solve each part step by step.

### (i) Finding four rational numbers equivalent to \(-\frac{2}{7}\):

1. **First Equivalent Number**:
- Multiply and divide by 2:
\[
-\frac{2}{7} \times \frac{2}{2} = -\frac{4}{14}
