Re-arrange suitably and find the sum in each of the following:
(i)`3/5+7/3+9/5+(-13)/(15)+(-7)/3`
(ii) `4/(13)+(-5)/8+(-8)/(13)+9/(13)`

Explanation

To solve the given problems, we will rearrange the terms suitably and then find the sum for each part step by step.

### Part (i): \( \frac{3}{5} + \frac{7}{3} + \frac{9}{5} + \left(-\frac{13}{15}\right) + \left(-\frac{7}{3}\right) \)

**Step 1: Group the fractions with the same denominator.**
- The fractions with denominator 5 are \( \frac{3}{5} \) and \( \frac{9}{5} \).
- The fractions with denominator 3 are \( \frac{7}{3} \) and \( -\frac{7}{3} \).
