Find four rational numbers between `2/3a n d4/5dot`

Explanation

To find four rational numbers between \( \frac{2}{3} \) and \( \frac{4}{5} \), we can follow these steps:

### Step 1: Convert the fractions to have a common denominator
We need to find a common denominator for \( \frac{2}{3} \) and \( \frac{4}{5} \). The least common multiple (LCM) of 3 and 5 is 15.

- For \( \frac{2}{3} \):
\[
\frac{2}{3} = \frac{2 \times 5}{3 \times 5} = \frac{10}{15}
