Question

Express 19.256 In p/q form. what
you say about the prime factors
can
of q ?​

Answer 1

we have x = 19.256 (bar on 256)       ------ (1)

Multiplying 1000 to both sides we get ,

1000x = 19256.256 (bar on 256)        ------- (2)

Now eq(1) and eq(2)

1000x - x = 19256.256 - 19.256

999x = 19237

x = 19237/999

p/q = 19237/999
