Well, isn't that a happy little question! Yes, indeed, 500 million is half of 1 billion. Just imagine a big, beautiful billion-dollar painting, and then picture carefully splitting it right down the middle to create two equal parts - one of those parts would be 500 million. Keep up the great work with your numbers, my friend!
500 million is equal to 500,000,000. It is half a billion or 5 hundred million.
500 million
500000 million.
It is: 500 times 1,000 = 500,000 which is half a million
500 million times 259 billion equals 129,500,000,000,000,000,000 (129.5 quintillion).
