Question

15. Express the following numbers in the form of p/q:
A)0.621621621....
B)15.7121212....​

Answer 1

Answer:

A . let x= 0.621621621            1

    1000x=621.621621                2

     2 - 1 = 1000x-x=621.621621-0.621621

     999x=621.000

      999x=621

      x =621/999

621/999 can be simplified by 3

207/333 can be simplified again by 3

69/111

B. let x=15.712712712                  1

  1000x=15712.712712              2

 2-1 = 1000x-x=15712.712712-15.712712712

 999x= 15697.0000

999x=15697

x=15697/999
