Question

$\frac{4}{7} + \frac{2}{9}$
​

Answer 1

$\longmapsto \bf \: \frac{4}{7} + \frac{2}{9}$

LCM of 7 and 9 is 63.

$\longmapsto \bf \: \frac{4 \times 9}{7 \times 9} + \frac{2 \times 7}{9 \times 7}$

$\longmapsto \bf \: \frac{36}{63} + \frac{14}{63}$

$\longmapsto \bf \: \frac{36 + 14}{63}$

$\longmapsto \bf \: \frac{50}{63}$

Therefore,the answer is 50/63.

Answer 2

Here is ur answer mate:-

4 2

----- + -----

7 9

• to add this fractions, we must first make its denominator same, i.e taking its LCM

LCM of 7 and 9 = 7×3×3 = 63

• now, making both's denominator as 63, we get,

36 14

------ + -----

63 63

36+14

-----------

63

50

------

63

hence, the sum of 4/7 and 2/9 is 50/63
