We can break this problem down into two questions.
- What is 47.1 x 106 equal to?
- Is 47,800,000 > 47.1 x 106?
To answer #1, we can see that 106 = 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000.
So, the problem becomes: 47.1 x 1,000,000 = 47,100,000.
Then, to answer #2, we notice that 47,800,000 is larger than 47,100,000.
Therefore, Taylor Swift has more Facebook fans than Selena Gomez.
