Find a rational number between `-2/3\ a n d1/4`

Explanation

To find a rational number between \(-\frac{2}{3}\) and \(\frac{1}{4}\), we can use the concept of the mean (average) of the two numbers. Here’s how to do it step by step:

### Step 1: Identify the two numbers
Let \(A = -\frac{2}{3}\) and \(B = \frac{1}{4}\).

### Step 2: Calculate the mean of the two numbers
The mean (or average) of two numbers \(A\) and \(B\) is given by the formula:
\[
