Hey there! :)

1st picture:

Change to common denominator:12

1 · 3 =  3
4 · 3 = 12

 5  · 1 =  5
12 · 1 =  12

 3   +  5   =  8  = 2
12     12  =  12 =  3

2nd picture:

Change to common denominator: 14

1 · 2 =  2
7 · 2 = 14

 3  · 1 = 3
14 · 1   14

 2  +  3  =  5  
14    14     14

3rd picture:

Change to common denominator: 15

1 · 3 =  3
5 · 3 = 15

2 · 5 = 10
3 · 5 = 15

10  + 3  = 13
15    15 = 15
