I want to know the answer to the following question:
What percentage of the population in Southeast Asia practice Islam?
All the background I'm provided with is that "Islam is the most widely practised religion in Southeast Asia, numbering approximately 240 million adherents which translate to about 40% of the entire population, with majorities in Indonesia, Brunei, Malaysia and in Southern Philippines with Indonesia as the largest and most populated Muslim country around the world.". Is that enough to answer the question?
