The repeal of the 21st amendment was unusual because it repealed a previous amendment. The 21st amendment voided the 18th amendment which outlawed alcohol.
The way the constitution works, you do not just "change an amendment." You can only repeal or change what an earlier amendment with another amendment. An example of repealing an earlier example is how the 21st Amendment nullifies the 18th Amendment (Prohibition). This is also the case with many amendments that had mentioned slavery and how they were altered through new amendments. On a side note, if you meant to say "How many times has the Constitution been changed by the Amendments" then your answer is 27. As the purpose of the amendments was to keep the Constitution as a living document and prevent it from becoming outdated and irrelevant in some cases.
Yes, through writing another amendment.
18th amendment
The ERA (Equal Rights Amendment) intended to prohibit all discrimination based on sex but it failed to win ratification. The Equal Rights Amendment was reintroduced in Congress on July 14, 1982 and has been before every session of Congress since that time. In the 110th Congress (2007-2008), it was introduced as S.J. Resolution. 10 (lead sponsor: Sen. Edward Kennedy, MA) and H.J. Res. 40 (lead sponsor: Rep. Carolyn Maloney, NY). These bills impose no deadline on the ERA ratification process. Success in putting the ERA into the Constitution via this process would require passage by a two-thirds in each house of Congress and ratification by 38 states. There were many reasons why this amendment failed, after sailing through the Congress. One of the major critics of the amendment were women themselves, who felt it was not necessary and would actually hurt the women's rights movement. There was also concern that the amendment would mean women could be drafted into the armed services, including combat duty. There was also concern that passage would effect the laws that protected women in the workforce.
Prohibition
The prohibition of an establishment of a national religion.
Congress can propose an amendment through the following methods: Two-thirds majority vote in both the House of Representatives and the Senate, followed by ratification by three-fourths of the state legislatures. Two-thirds majority vote in both the House and the Senate, followed by ratification through conventions held in three-fourths of the states. Either of these methods must be used to propose an amendment, which then goes through the ratification process.
Amendment 21 counteracted against amendment 18. Amendment 18 was to stop alcohol trade and instead of repealing or canceling amendment 18 they just passed amendment 21 which allowed there to be alcohol trade. Amendment 21 was adopted in 1933 took away prohibition
According to Article V, two provisions, one which has expired, the other still in effect may not be amended. The first was importation of slaves the prohibition of which was forbidden until the early 1800's. The second is that no state may, without its own consent, be deprived of its equal representation in the senate. As the Constitution mandates an amendment is passed at three fourths ratification of the states this effectively means this provision of the Constitution cannot be amended as it would require more ratification votes than the Constitution permits meaning the amendment itself would be unconstitutional.
Both were products of "Prohibition", established to outlaw the production, sale, and transport of "intoxicating liquors" (alcoholic products and beverages) by the 18th Amendment to the United States Constitution (ratification certified 16 January 1919; the amendment took effect 17 January 1920). The enforcement of Prohibition was provided for by Congress via the National Prohibition Act (hence the name Prohibition); the Act was also known as the "Volstead Act" in reference to Andrew Volstead, Chairman of the House Judiciary Committee, who managed the legislation's progress through Congress. Prohibition spawned "speakeasies", or illegal drinking establishments, and "bootleggers", or providers of illicit alcohol products, in great numbers throughout the country. These were both a reaction to the continued demand for alcohol by a large majority of the citizenry despite any legal prohibition to the contrary, and represented some of the most visible of the many entrepreneurial business efforts to supply said demand. The widespread disregard for this law of the land ("speakeasies" proliferated in virtually every city, town, and village in the country, while "bootleggers" were even more widespread, and large-scale such operations spawned much of the great potency of---as well as the establishment of much of the initial funding enjoyed by---organized crime organizations; some of the same criminal organizations whose rise was rooted in Prohibition continue to plague America to the present day) and the total lack of success in the objectives of Prohibition resulted in even some of it's most ardent supporters calling for it's repeal. In what remains the only instance of a Constitutional Amendment being reversed, Prohibition was repealed by the 21st Amendment (ratified 5 March 1933).
The first through tenth amendments were an agreement by the Continental Congress to add them after the ratification of the original Constitution. The first amendment, and all of the Bill of Rights for that matter, wasnt necessarily proposed by one person, but by many members of the Congress.

Speakeasies and bootleggers were a result of the Volstead Act, which started a period known as Prohibition. During that time, production, transport, and sale of alcohol was illegal, so bootleggers got alcohol illegally, and people could hide the fact that they were drinking alcohol by drinking at speakeasies.
United States Constitution established the popular election of United States Senators by the people of the states. Under which senators were elected by state legislatures.
An amendment is an addition, deletion of modification of the contents of the U.S. Constitution. It can be ratified through a majority vote of two-thirds in both legislature houses, and by a constitutional convention.
Yes, it existed until 1865 when the GOP led congress at the time pushed through the 13th Amendment and it was ratified by 3/4 of the US States. The last of 27 states needed for ratification was Georgia which ratified the amendment December 6, 1865. The Constitutional amendment banned slavery and indentured servitude completely over Democrat objections.
It was repealed through the actions of state conventions.
