It is One hundred and fify trillion in the modern US usage It is One hundred and fifty billion if you use the old English billion.
Yes, both are correct.
1km is 1000 meters. 150 million km is 150 000 million meters. 150 000 million meters = 150 billion meters. (Careful I'm talking about 150 with 9 zeroes (150 000 000 000). Billion is the US name for that, but other country's names can vary.)
Fifteen quadrillion.
Forty trillion
In North American English, that would be six septillion. In UK English, that would be six quadrillion.

You write it: 150 000 000.
1km is 1000 meters. 150 million km is 150 000 million meters. 150 000 million meters = 150 billion meters. (Careful I'm talking about 150 with 9 zeroes (150 000 000 000). Billion is the US name for that, but other country's names can vary.)
7 zeros 150 000 000
150000000000000 150000000000000
150 kHz is equal to 150,000 Hz, and 20 MHz is equal to 20,000,000 Hz.
150 as a percentage of 1 million = 150*100 / 1 000 000 = 15/1000 = 0.015 %
the answer to 150 times 2000 is 300 000
£150 000 or $200 000
Fifty quadrillion.
