Answer 2

Answer:

13/15

Step-by-step explanation:

1. First find LCM of 12 and 20

LCM is 60

2. Multiply numerator and denominator with same number which gives denominator equal to 60

5×5/12×5 = 25/60 ....(1)

9×3/20×3 = 27/60 ...(2)

3. Now add (1) and (2)

5/12×5/5 + 9/20×3/3 = 25/60 + 27/60

5/12 + -9/20 = 25 + 27 / 60

= 52/60

= 13/15
