2 million is a large number to multiply, sure, but do not let that scare you. Million is just a label. Do the multiplication normally (disregarding the scary "millions" word) and then tack the units on the end of the answer.
2 x 150 = 300
Therefore, 2 million x 150 = 300 million.
first, take away the million and just do 150*2=300 and then bring back the million
so the answer is 300 million
