Answer:

Given,

$\frac{7}{9} - \frac{2}{5}$

To Find :-

Simplify it.

Solution :-

$\frac{7}{9} - \frac{2}{5}$

L.C.M of 9 , 5 = = 45.

Equating the denominaters :-

$\frac{7}{9} = \frac{7}{9} \times \frac{5}{5}$

$= \frac{35}{45}$

$\sf\therefore \dfrac{7}{9} = \dfrac{35}{45}$

$\frac{2}{5} = \frac{2}{5} \times \frac{9}{9}$

$= \frac{18}{45}$

$\sf\therefore \dfrac{2}{5} = \dfrac{18}{45}$

Now,

$\frac{7}{9} - \frac{2}{5} = \frac{35}{45} - \frac{18}{45}$

$= \frac{35 - 18}{45}$

$= \frac{17}{45}$

$\sf\therefore \dfrac{7}{9}- \dfrac{2}{5} = \dfrac{17}{45}$
