Studies of school-based substance abuse prevention programs
in the 1970s revealed that students who knew more about drugs and their effects

Answer:
The identity property of multiplication states that a number multiplied by 1 will equal itself.
1.) So, you may have an equation like this:
(4/4) x (3/4) = (12/16) ---simplify---> (3/4)
To find this answer this way, I multiplied the numerators together and the denominators together. Then, I simplified the fraction.
2.) If you were to use the identify property of multiplication, the equation would look like this:
(4/4) x (3/4) ---simplify---> 1 x (3/4) = (3/4)
By recognizing that (4/4) equals 1, the answer can be more easily found through the use of the identity property.
I hope this was what you were looking for!
The Qin introduced common coinage, meaning a form of ´fiat´ currency backed by the central government. It was called a ´ban liang´, and they could be issue by local nobles as well as by the emperor. A system of coinage is important for the unification of a massive empire because it facilitates trade and the recollection of revenue for the central government. As such, it becomes easier to raise a common army, which is essential for unification of different warring states.
