Question

0.254254254 expressed as p by q (HCF of p, q is 1 )then the value of p+q

Answer 1

Answer:

254 / 999

Step-by-step explanation:

When you have a recurring pattern like this, it's as simple as writing the recurring chunk over the number with the corresponding number of 9s.

To finish the exercise, you just need to check that HCF(254, 999) = 1.  To this end, notice that 999 = 9 x 111 = 9 x 3 x 37, so its prime factors are 3 and 37, while 254 = 2 x 127, and these are its prime factors.
