Population of Scotland 5.295 million
Population of UK 63.23 million.
Scottish population as a percentage = 63.23/5.295 =11.941%

Scottish MPs 59
Westmister MPs 650
Scottish MPs as a percentage of Westminster MPs = 650/59 = 11.01%

??????? Scottish population as a percentage should be (5.295/63.25)*100 = 8.37% You've canlculated it as a fraction of the population. One eleventh is approximately 8%. One eleventh is not 11%
