2/3 + 3/4 

Rules 
1. Bring both terms to a common denominator (bottom number) 
2. The corresponding numerator (top0 must be multipled by the same factor 
3. Add the numerators (top) . 
4. Reduce to a mixed number. 

2(4) / 3(4) + 3(3) / 4(3) 
8/12 + 9/12 
17/12 
1 5/12 

2/7 + 5/9 
2(9)/7(9) + 5(7)/(9(7) 
18/63 + 35/63 
53/63 

Will not reduce because '53' is a prime number. 


2/13 + 1/12 
2(12) / 13(12) + 1(13)/12(13) 
24/156 + 13/156 
37/156 
Will not reduce because '37' is a prime number.

Hope this Helps:)
