2,500,000,000 = 140*(3/5)t
Therefore (3/5)t = 2,500,000,000/140
=> t*log(0.6) = log(2,500,000,000/140)
=> t = log(2,500,000,000/140)/log(0.6) = -32.6881
Yes!
Eight hundred fourteen billion, seven hundred forty million.
144,000,000,000 is one hundred and forty-four billion
10,340,000,000 is ten billion, three hundred and forty million
Assuming one billion equals one thousand million, 24% of 301 billion = 0.24 x 301,000,000,000 = 72,240,000,000 or seventy-two billion two hundred and forty million.
Eleven billion, seven hundred forty million.
Eight hundred forty-two billion, seven hundred million or 8.427 billion.
Six hundred forty-two billion, six hundred million, two thousand, five hundred forty.
ninety eight trillion four hundred fifty three billion two hundred thirty nine million eighty seven thousand five hundred forty six
One more than two billion three hundred forty two thousand two hundred and two, or 2,000,342,203
7 billion * 20 = one hundred forty billion
1,445,445,445 = one billion, four hundred forty-five million, four hundred forty-five thousand, four hundred forty-five.
