375 billion x 200 billion = 75,000 billion billion = 7.5 x 1022 = 75,000,000,000,000,000,000,000

Depends which billion you are using. A longscale usage billion is 1,000,000,000,000 (1012)or a million million, whereas a shortscale billion is one thousand million, like 1,000,000,000 (109).
375*200=75,000
Short scale, a billion times a billion = 1,000,000,000,000,000,000 or 1018
Long scale = 1,000,000,000,000,000,000,000,000 or 1024
Those * 75,000 >
Short  75,000,000,000,000,000,000,000 or 7.5*1022
Long  75,000,000,000,000,000,000,000,000,000 or 7.5*1028
You probably want the short scale one, but they're both pretty big numbers.

In a 200 billion, there are 11 zeros. This is because a billion is equivalent to one thousand million, which has 9 zeros. Therefore, when you multiply 200 by a billion, you get 200,000,000,000, which has 11 zeros.
5% of 200 billion= 5% * 200000000000= 0.05 * 200000000000= 10,000,000,000 or 10 billion
