What fraction is needed to propose amendments to the constitution and what fraction was needed to pass those propasals

The other method of passing an amendment requires a Constitutional Convention to be called by two-thirds of the legislatures of the States. That Convention canpropose as many amendments as it deems necessary. Those amendments must be approved by three-fourths of the states.

The fraction that is needed to propose is 1/2 because it is origanally a fraction of the division table. The fraction that is needed is also 1/2 so you add 1/2 plus1/2 to give you2/2. Simplify it to 3. Hope this helped!
