In order to solve this i'd have to know what x equals?? does it tell you?
This is just converting billion to million, vice-versa.
1 million = 0.001 billion
1,200 billion = 1,200,000,000,000
So once it is converted, the answer will be,
1.2 x 10^15 million.
4050 divided by 3 = 1350
There is 4050 people in an arena and there is 3 sections of seats. How many people are in one section of seats?
