<h3>Answer : </h3>

$\Large \pink{\tt \dfrac{35}{36}}$

<h3>Solution :</h3>

$\tt \dfrac{3}{4} + \dfrac{2}{9}$

By taking LCM = 4 × 9 = 36

$\tt = \dfrac{3 \times 9}{4 \times 9} + \dfrac{2 \times 4}{9 \times 4}$

$\tt = \dfrac{27}{36} + \dfrac{8}{36}$

$\tt = \dfrac{27 + 8}{36}$

$\tt = \dfrac{35}{36}$

$\pink{\tt \therefore \: Answer \: is \: \dfrac{35}{36}}$
