Answer:
2 000 000 000 (2 billion)
Step-by-step explanation:
To round to the nearest billion we take a look at the following number 234 569 000, in this case we have 2 hundred millions which is less than 500 million (minimum value to round up to 3 billion) so in this case we round this number to 2 billion.
Let's take another example to see when to round up: 2 534 569 000 would be rounded to 3 billion for example.
