The Prime Meridian is an imaginary line on the Earth between the north and
south poles. 1/7 is a fraction. They're not connected, related, or associated
in any way whatsoever. You've accidentally gotten your geography homework

The prime meridian is defined as the line of 0° longitude on Earth's surface. The fraction 1/7 does not directly relate to the prime meridian.
As your are positioned at 105E of Prime Meridian, you are on a easterly track from prime meridian (ie. GMT time) therefore LMT (Local Mean Time ) at 105E can be calculated as105E\15= 0700hrs ( results as per scientific calculator )Therefore LMT at 105E would be GMT at 105E + 0700ie 0600+0700=1300hrs.Ans Local Mean Time at 105E = 1300hrs
If it is 1p.m. where you are, it would be 7 p.m. in Norway. Norway is in the Central European Time Zone, which is six hours ahead of Eastern Standard Time.
All of China switched to UTC+8 in 1980. UTC+8 is the local mean time at 120 degrees east longitude. Unofficially, the two westernmost Chinese provinces, Tibet and Xinjiang, use UTC+6, which is the local mean time at 90 degrees east longitude.
As of September 2021, the largest known prime number is 2^82,589,933 − 1. It was discovered on December 7, 2018, through the Great Internet Mersenne Prime Search (GIMPS) project.
The longitudinal extent of India is 30 degrees. The sun rises in the east and sets in the west. It takes 4minutes for the sun to move across 1 longitude. Thus the eastern most point of India would be 2 hours ahead of the western most point (30X4=120 minutes) , in accordance with the local time. This difference in time might create confusion in air and rail timings and so many other things across the two states. To avoid this confusion a longitude passing through the mid point of 68 degrees 7 minutes (western most longitude) and 97 degrees 25 minutes (eastern most longitude) is taken as the standard prime meridian ofIndia. The time at the standard meridian 82 degrees 30 minutes which passes through Mirzapur in UP is taken as the standard time of India , followed all over the country.
