How much is Two thirds of a billion?

Answer 1

Well, honey, two-thirds of a billion is 666.67 million. So, if you're looking to split a billion into thirds, you're gonna end up with about $666.67 million in your pocket. Math can be a real pain sometimes, but hey, that's the beauty of numbers, right?

Answer 2

It can be written accurately and completely as a fraction, but not as a decimal.

2/3 of 1 billion = (2/3) x (1,000,000,000) = (2,000,000,000 / 3) = 666,666,666.666 (rounded, repeating)
