Dude that is so much more difficult than just splitting it and then adding.
Try it like this....10% of 200....Easy, that's 20. so 20% = 10% + 10% -> 20 + 20 = 40.
We're doing the same thing, but just thinking about it a different way. Remember that for us the mental jump from 10% of 200 = 20 is indeed an easy one. It might not be for everyone not intimately familiar with percentages. I'm trying not to assume too much going in.
Also, splitting and adding immediately is not an easy extrapolation to unusual percentages. Sure 20% = 10% + 10% of 200 is easy. What's 19% of 200? Okay, 10% + 9%. What's 9% of 200, off the top of your head? Hmm..did you multiply 2 by 9 and say 18? Well, that's because you mentally did what I'm suggesting, but didn't consciously think about it.
