Ingat konsep operasi pecahan:

table attributes columnalign right center left columnspacing 0px end attributes row cell a over b plus-or-minus c over b end cell equals cell fraction numerator a plus-or-minus c over denominator b end fraction end cell row cell a over b divided by c over d end cell equals cell a over b cross times d over c end cell row cell a over b cross times d over c end cell equals cell fraction numerator a d over denominator b c end fraction end cell row cell a b over c end cell equals cell fraction numerator open parentheses a c close parentheses plus b over denominator c end fraction end cell end table  

Ubahlah pecahan campuran ke pecahan biasa kemudian dahulukan operasi pembagian sehingga:

Dengan demikian hasil dari 2 over 3 plus 1 3 over 4 minus 2 1 half divided by 3 1 third adalah 5 over 3.
