There are 9 zeros in 75 billion in the US and current UK short scale. This is 75,000,000,000. There are 12 zeros in 75 billion in the older UK long scale. This is 75,000,000,000,000.
75,000,000 = 75 million and so there are six of them
7500 followed by 9 zeros; that is 75 followed by 11 zeros in all
