For an amendment to be ratified, it must be approved by what fraction of the states?

Explanation:

It's 2/3 of the house and senate.

It then has to go to the state legislatures. 2/3 of those houses have to call for a constitutional amendment.

Article five of the constitution has a more detailed description, and the constitution looks like it has been changed over the years. However this is the current method of passing an amendment.

answer-the island had airfields that the u.s. military needed.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
