Answer:

Explanation:

1: Make 2/8 and 3/12 have equal denominators (bottom numbers). So times each fraction by the other fraction denominator to create common denominators.

2: 2/8 (both numbers 2 and 8) times by 12

and 3/12 (both numbers 3 and 12) times by 8

3: you will then get the new fractions of 24/96 + 24/96

4: now that your denominators match you can add your numerators " 24+ 24"

5: to get another new fraction of 48/96 (final answer without reducing)

6: If must to reduce than divide top and bottom by 8 to get 6/12 to see it can reduced into 1/2 because 6 is half of 12

7: final answer ; either 48/96 without reducing(simplifying) or 1/2 with reducing (simplifying)
