Answer 2

Given: Sum of two rational numbers is $\frac{4}{5}$

           One of the numbers is $\frac{2}{15}$

To find: The other number

Let: The other number be $x$

Solution: Given that sum of two rational numbers is $\frac{4}{5}$ and one of the numbers is $\frac{2}{15}$.

According to the given question and assumption made,

∴ $x + \frac{2}{15} = \frac{4}{5}$

⇒ $x = \frac{4}{5} - \frac{2}{15}$

⇒ $x = \frac{12 \ - \ 2}{15} = \frac{10}{15} \ or \ \frac{2}{3}$

Hence, the other number is $\frac{2}{3}$ .
