Nope - that's not how percentages work. 10% more is 10% of the other number - i.e. if the PS3's 45% was 100 units, 10% more is 10% of 100 - i.e. another 10 units - get it?
Right now we know the percentage split - but not how much more empirically 360 sold as we need the actual sales number to see that.
Try to be reasonable... its easier than you think...
