\frac{15 + 20}{7} = \frac{15}{5} + \frac{12}{6}\\\\\frac{35}{7} = 3 + 2\\ 5 = 3 + 2\\5 = 5

The Constitution of the United States of America is the central instrument of American government and the supreme law of the country. For more than 200 years it has guided the evolution of governmental institutions and has provided the basis for political stability, individual freedom, economic growth and social progress.
The American Constitution is the world’s oldest written constitution in force. It is one that has served as the model for a number of other constitutions around the world. The Constitution owes its staying power to its simplicity and flexibility. Originally designed to provide a framework for governing four million people in 13 very different colonies along the Atlantic coast, it now with only 26 amendments serves the needs of more than 240 million people in 50 even more diverse states that stretch from the Atlantic to the Pacific Ocean.
A draft of the Constitution document emerged in 1787. The 13 British colonies declared their independence from England in 1776. While still at war, the colonies - now calling themselves the United States of America - drafted a compact which bound them together as a nation. The document, designated the “Articles of Confederation and Perpetual Union”, was adopted by a Congress of the states in 1777, and formally signed in July 1778. The Articles became binding when they were ratified by the 13th state, Maryland, in March 1781.
