Answer
Given: $2.\overline{36}+0.\overline{23}$
Let
$\text{x}=2.\overline{36} \ ...(\text{i})$
$\text{y}=0.\overline{23} \ ...(\text{ii})$
First we take x and convert it into $\frac{\text{p}}{\text{q}}$
100x = 236.3636 ...(iii)
Subtracting (i) from (iii) we get
$99\text{x}=234$
$\Rightarrow\text{x}=\frac{234}{99}$
Similarly, multiply y with 100 as there are 2 decimal places which are repeating themselves.
100y = 23.2323 ...(iv)
Subtracting (ii) from (iv) we get
$99\text{y}=23$
$\Rightarrow\text{y}=\frac{23}{99}$
Adding x and y we get
$2.\overline{36}+0.\overline{23}=\text{x}+\text{y}=\frac{234}{99}+\frac{23}{99}=\frac{257}{99}$
Let
$\text{x}=2.\overline{36} \ ...(\text{i})$
$\text{y}=0.\overline{23} \ ...(\text{ii})$

$\Rightarrow\text{y}=\frac{23}{99}$

$2.\overline{36}+0.\overline{23}=\text{x}+\text{y}=\frac{234}{99}+\frac{23}{99}=\frac{257}{99}$
