If you take the time to calculate it, its actually easy:

Divide 13 million by 2 = 6.5 million

Now subtract 0.15*6.5 million = 5.525 million

Now add the 0.15*6.5 million you just subtracted to 6.5 million again (because if you subtract 15% of one half and add it to the second, there is a 30% difference between the two parts)= 7.475 million
