Adding/subtracting fractions, you need a common denominator.
Multiplying fractions, multiply numerators, multiply denominators.
Dividing by a fraction is equivalent to multiplying by its reciprocal.

1%2F2%2B%282%2F3%29%2F%283%2F4%29-%284%2F5%29%285%2F6%29=1%2F2%2B%288%2F9%29-%282%2F3%29
Use a common denominator of 18
%281%2F2%29%289%2F9%29=9%2F18
%288%2F9%29%282%2F2%29=16%2F18
%282%2F3%29%286%2F6%29=12%2F18

Hi,

If I am understanding your question properly:

%281%2F2%29+%2B+%282%2F3%29%2F%283%2F4%29-+%284%2F5%29%285%2F6%29

Dividing by (3/4) is the same as Mulitplying by (4/3)

%281%2F2%29+%2B+%282%2F3%29%2A%284%2F3%29-+%284%2F5%29%285%2F6%29 

%281%2F2%29+%2B+%288%2F9%29-+%2820%2F30%29

%281%2F2%29+%2B+%288%2F9%29-+%282%2F3%29

Need common denominators to perform the additions and subtractions properly

%289%2F18%29+%2B+%2816%2F18%29-+%2812%2F18%29
