Question

Express o.31 in the form p/q are integers and q is not equal to zero

​

Answer 1

Answer:

Let x = 0.313131......----->>[1]

Periodicity is 2

so multiply by 100 on both sides.

100x = 31.313131.....----->>[2]

Now subtract equation [1] from [2]

100x = 31.313131.....

(-) x = 0.313131....

_______________

99x = 31.0000

__________

now x = 31÷99

i.e. o.31 bar in form of p/q is

31/99

hope it helps
