Following real numbers are expressed in decimal form. Find whether they are rational or not. If rational. express them in form p/q. Comment on factors of q:

Let × = 3. 456789123456…………eq(1)


As there are 9 repeating digits. So we multiply by 109


109 × = 3456789123. 45678912345678…. …..eq(2)


Subtracting (1)from(2):


99999999 × = 3456789120
