Mike, who has 6 video games, has half as many games as Paul.
It's pretty easy, it means that Paul has twice as many games as Mike has. But mathematically we can write it down as:
6 = 1/2 x / * 2 (both sides)
x = 12
I hope it helped :)
If Mike has half as many as Paul, then Paul has twice as many as Mike.
Mike = Paul/2 so 6 = Paul/2
Multiply both sides by 2
12 = Paul
or
Paul = Mikex2
Paul = 6x2
Paul = 12
Hope that helps
