Half of 2 billion is 1 billion. To find half of a number, you divide it by 2. In this case, dividing 2 billion by 2 gives you 1 billion. This is because half of any number is equal to dividing that number by 2.
As a number it is: 28,500,000,000
Half of 6.5 billion is 3,250,000,000 (3.25 billion).
1 and one half billion can be written as 1.5 billion.
One half billion divided by 16 is 31,250.
500 million
Half of 2 billion is 1 billion. To find half of a number, you divide it by 2. In this case, dividing 2 billion by 2 gives you 1 billion. This is because half of any number is equal to dividing that number by 2.
As a number it is: 28,500,000,000
Half of 6.5 billion is 3,250,000,000 (3.25 billion).
The half-life of Rubidium-87 is about 48.8 billion years. To determine the number of half-lives in 4.6 billion years, you divide the age of the Earth by the half-life of Rubidium-87: 4.6 billion years / 48.8 billion years ≈ 0.0943 half-lives. Thus, the age of the Earth represents approximately 0.09 half-lives of Rubidium-87.
5,500,000,000
Half of an American billion is 500,000,000 (500 million). Half of a British billion is 500,000,000,000 (500 thousand million).
funny enough, half a billion
Half of one billion is 500 million. To find half of a number, you simply divide it by 2. In this case, dividing one billion by 2 gives you 500 million. This is because one billion is equal to 1,000 million, so half of that would be 500 million.
1 and one half billion can be written as 1.5 billion.
1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years.
The half-life of potassium 40 is 1.25 billion years. This is because the number of atoms decreased by half (from 50 to 25) in this time period, indicating one half-life has passed.
