billion people. Country B is next with 
billion people. How many more people does Country A have than Country B?
Country A has the largest population on Earth, with
Tap to reveal answer
To find how many more people Country A has than B we need to subtract the number of people in Country B from that in Country A.
From here we will convert the units from billion to million.
0.3 billion is equivalent to 300,000,000
