Answer 2

$\dfrac{22}{7} =3.\overline{142857}$    or

22/7  =   3.142857...

Given:

• 22/7

To Find:

• Convert in decimal

Solution:

• Any number in the form of p/q  where p and q are co primes.
• if q has only prime factors of 2 and 5 then it is terminating decimal.
• if q has prime factors other than 2 and 5 also then its non terminating recurring decimal

22/7  has denominator 7 which is other than 2 and 5 hence it non terminating recurring decimal.
