Like all other numbers, fractions number can be added, subtracted, multiplied, and divided.
Addition

a/b + c/d = ad/bd + bc/bd = (ad + bc)/bd
example: 3/4 + 1/6 = 18/24 + 4/24 = 22/24 = 11/12
Subtraction

a/b  c/d = ad/bd  bc/bd = (ad  bc)/bd
example: 3/4  1/6 = 18/24  4/24 = 14/24 = 7/12
Multiplication

a/b · c/d = ac/bd
example: 3/4 · 1/6 = 3/24 = 1/8
Division

(a/b)/(c/d) = ad/bc
example: (3/4)/(1/6) = 18/4 = 9/2
