3. 0.1 billion
4. 10 billion

Task  : 

How many billion are in the next slide?

1. 1 billion
2. 0.1 billion
3. 10 billion
4. 0.01 billion

Explanation 

It is about 100 million excuses.         Let's analyse this:

1 billion          =  1 000 million = 1 000 000 000,  so

 0.1 billion      =     100 million  =    100 000 000 

So the answer to the question is:

0.1 billion.
