The volume of the Earth is approximately $$7.67\times 10^{-7}$$ times the volume of the Sun. Express this figure in usual form.
In standard form of a number we put decimal after first digit and remaining power is written as power of $$10$$
Given, volume of the Earth $$=7.67\times 10^{-7}$$ times the volume of the Sun, is in the standard form.
In usual form we have to add $$7$$ more decimals because of $$10^{-7}$$
So,
Usual form of $$7.67\times 10^{-7}=0.000000767$$
We have placed decimal $$7$$ places towards the left of original position.
