Lcm will be 21 so multiply
2x7/3x7 , 1x3/7x3
We will multiply numerator also when denominator is multiplied
So
14/21,3/21
Now as per question add
14+3/21
17/21
Hence answer is 17/21
2x7/3x7 , 1x3/7x3
We will multiply numerator also when denominator is multiplied
So
14/21,3/21
Now as per question add
14+3/21
17/21
