9 / 18 = 1 / 2

3 9 / 18 = 3 1 / 2

3 * 18 = 54

1 / 3 = 18 / 54

1 / 2 = 27 / 54

5 1 / 3 + ( - 3 9 / 18 ) =

5 1 / 3 - 3 9 / 18 =

5 1 / 3 - 3 1 / 2

5 + 18 / 54 - ( 3 + 27 / 54 ) =

5 - 3 + 18 / 54 - 27 / 54 =

2 - 9 / 54 =

2 - 9 / ( 9 * 6 ) =

2 - 1 / 6 =

1 + 1 - 1 / 6 =

1 + 6 / 6 - 1 / 6 =

1 + 5 / 6 =

1 5 / 6

1st of all its easier if u turn the fractions to improper frac.

16/3- 63/18

then, u get the least common ddenominator which is 18

then,your equation should be

96/18- 63/18

then subtract since the 2nd fraction is negative.... and you get 33/18 or 1 and 5/6

hope this helped:)
