Answer: ![10^{-6}](https://tex.z-dn.net/?f=10%5E%7B-6%7D)
Explanation:
As we are given to calculate :
= ?
1 million is equal to = ![10^6](https://tex.z-dn.net/?f=10%5E6)
1 trillion is equal to = 1 million million = ![10^{12}](https://tex.z-dn.net/?f=10%5E%7B12%7D)
Putting in the values we get:
![\frac{1 million}{1 trillion}=\frac{10^6}{10^{12}}=10^{6-12}=10^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%20million%7D%7B1%20trillion%7D%3D%5Cfrac%7B10%5E6%7D%7B10%5E%7B12%7D%7D%3D10%5E%7B6-12%7D%3D10%5E%7B-6%7D)
Thus the correct answer is ![10^{-6}](https://tex.z-dn.net/?f=10%5E%7B-6%7D)
