Question

Mike, who has 6 video games, has half as many games as Paul.

Answer 1

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 :)

Answer 2

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
