There are two correct answers to this question:
15 (in the USA and in any countries that use "short scale" naming conventions)
Or
24 (in countries that use "long scale" naming conventions)
To work out the number of zeros from the scales:
→ billion: bi implies 2 → 2 x 6 = 12 zeros
→ trillion: tri implies 3 → 3 x 6 = 18 zeros
→ quadrillion: quad implies 4 → 4 x 6 = 24 zeros
→ quintillion: quin implies 5 → 5 x 6 = 30 zeros
etc
→ billion: bi implies 2 → 3 x (2 + 1) = 3 x 3 = 9 zeros
→ trillion: tri implies 3 → 3 x (3 + 1) = 3 x 4 = 12 zeros
→ quadrillion: quad implies 4 → 3 x (4 + 1) = 3 x 5 = 15 zeros
→ quintillion: quin implies 5 → 3 x (5 + 1) = 3 x 6 = 18 zeros
etc
→ quadrillion: quad implies 4 → 3 x (4 + 1) = 3 x 5 = 15 zeros.
46 million has 6 zeros, like this: 46,000,000
There are 1000 sets of 1 million years in a billion years.
one thousand 1,000,000 x 1,000 = 1,000,000,000 = 1 billion
Googolplexian: The worlds largest number with a name. A "1" followed by a googolplex of zeros Googolplex: The second largest number with a name. A "1" followed by a googol of zeros Googol: A large number. A "1" followed by one hundred zeros. There are infinitely many numbers, so there is no longest number.
2507 billion
There are nine zeros in a billion.
how many zeros in one billion
There are 9 zeros in one billion
1 billion has 9 zeros.
In 90 billion, there are 9 zeros. This is because a billion has 9 zeros (1,000,000,000), and when you multiply 90 by a billion, you get 90 billion, which retains the 9 zeros from the billion.
A billion is 1 followed by nine zeros 70 billion thus has 10 zeros 70,000,000,000
There are 9 zeros in 16,000,000,000 which is 16 billion
There are 8 zeros in 22.5 billion, which is 22,500,000,000
There are nine zeros in a billion (1,000,000,000) and twelve zeros in a trillion (1,000,000,000,000).
Seven zeros.
Eight zeros.
9 zeros
