    Conversion: 9 1/6 = 9 · 6 + 1

    6

    = 55

    6

    Conversion: 6 1/4 = 6 · 4 + 1

    4

    = 25

    4

    Add: 55

    6

    + 25

    4

    = 55 · 2

    6 · 2

    + 25 · 3

    4 · 3

    = 110

    12

    + 75

    12

    = 110 + 75

    12

    = 185

    12

    The common denominator you can calculate as the least common multiple of the both denominators - LCM (6, 4) = 12

    Conversion: 4 5/6 = 4 · 6 + 5

    6

    = 29

    6

    Add: 185

    12

    + 29

    6

    = 185

    12

    + 29 · 2

    6 · 2

    = 185

    12

    + 58

    12

    = 185 + 58

    12

    = 243

    12

    = 81

    4

    The common denominator you can calculate as the least common multiple of the both denominators - LCM (12, 6) = 12
