Depends how roughly you want it.
It is generally accepted in the science community that the Earth is 4.54 billion years old.
The current best estimate for the age of the Earth is 4.567 Billion years old. Please see the related link.
== == The age of the Earth is roughly 4.6 billion years.
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
Roughly 167 million years old. The most recent scientific age of the Earth is 4.567 billion years.
The age of the Solar System is estimated to be about 4.568 billion years; Earth is almost as old - estimated at 4.54 billion years. The age of the Universe is estimated to be about 13.798 billion years. Thus, the ratio is about 33%.

Earth formed approximately 4.5 billion years ago, not 50 billion years ago or 5 billion years ago. This age estimate is based on radiometric dating of meteorites and rocks on Earth.
No. The universe itself is "only" about 13.7 billion years old. Earth is about 4.55 billion years old.

it is 4.54 billion years...
The Earth is at least 4.4 billion years old.
The half-life of Rubidium-87 is about 48.8 billion years. To determine the number of half-lives in 4.6 billion years, you divide the age of the Earth by the half-life of Rubidium-87: 4.6 billion years / 48.8 billion years ≈ 0.0943 half-lives. Thus, the age of the Earth represents approximately 0.09 half-lives of Rubidium-87.
The universe is 13.7 billion years old & Earth is 4.5 billion years old.
Roughly 167 million years old. The most recent scientific age of the Earth is 4.567 billion years.
