16 billion
The number 1 billion can be written as the Roman numeral [M] with a horizontal bar above it (which I can't write with my keyboard). Do that four times for four billion, then add VI which is six.
1,000,000,000 * 0.004 = 4,000,000
thirty four thousand billion!!
Four hundred trillion
Four billion.
one billion times larger
It is four billion.
124 times 1 billion is 124 billion.
Six thousand four hundred and seventy-four billion.
1,000,000,000 x 1,000,000,000 x 1,000,000,000 = 1,000,000,000,000,000,000,000,000,000
3.4 billion times 0.9 is 3,060,000,000 or 3.06 billion.
0.4 billion is four tenths of one billion. One tenth of a billion is 100 million. (A billion is one thousand millions.) So four tenths of a billion is 400 million, or 400,000,000.
