Facts and Figures
1) There are around 650 million mobile phone users in Africa How many more users is that
compared to the 76 million UK users?
650 million – 76 million = 574 million
2) 1 person in 5 in Africa has electricity. If the population is 1 billion, how many people have
and do not have electricity?
1billion ÷ 5 = 200 million
Remember, 1 Billion is 1000 million = 1,000,000,000
So 200 million have electricity and 800 million don’t.
3) Only 15% of Africans have access to the internet. If the population is 1 billion, how many
people is that?
1 billion ÷ 100 = 10,000,000
10,000,000 x 15 = 150,000,000
