What happened at southern democrats gained power?

When southern Democrats gained power, they put an end to Reconstruction.

Explanation:

The end of Reconstruction was a staggered process, and the period of republican control ended at different times in different states. With the Compromise of 1877, military intervention in Southern politics ceased and Republican control collapsed in the last three state governments in the South. This was followed by a period that white southerners called "Redemption," during which state legislatures dominated by whites enacted the Jim Crow laws and, beginning in 1890, deprived the majority of African Americans and many poor whites of a combination of constitutional amendments and electoral laws. The white memory of the Reconstruction of the Southern Democrats played an important role in the imposition of the system of white supremacy of segregation, of second-class citizenship for African-Americans using the laws known as Jim Crow laws.

part a. there were 250 teenagers surveyed (100% of tenagers = 250)therefore 1 % = 250/100 = 2.5 76% = 1% x 76 = 2.5 x 76 = 190 teenagers of the 250 surveyed liked burgerspart b: jane surveyed 25% (which is equal to 50 teenagers, i.e. a quarter of the teenagers surveyed is 50) to get 100% we simply get 4 quarters, i.e. multiply 50 by 4 = 200 teenagers were surveyed by jane. part c: it is impossible to give an example where a percentage is greater than 100%, since, by definition , percentage means "per 100".
