Question 1084573: Here's the question I'm working on:
The percentage of Republicans in the House of Representatives decreased from 53.3% in 2007 to 46.4% in 2009.
By how many percentage points did the percentage of Republicans in the House drop between 2007 and 2009? What was the percentage decrease of the percentage of Republicans in the House of Representatives between 2007 and 2009?
For the first part, I did: 53.3% - 46.4% =
6.9 %pts
For the second part, my math was:
.464 - .533= .069
.069/.533 = .12945590 =
-12.95%
Is this the correct way to do it? Thank you in advance!

Great job!!
Your 1st answer is 100% correct!
Your 2nd answer is also 100% correct, which I'm surprised because MANY, MANY people do the calculation INCORRECTLY.
You set up everything correctly as you applied the  , or the "NOO" formula.
Note that the negative in the - 12.95%, which again is ABSOLUTELY the correct way to do it, signifies a REDUCTION/DECREASE from an earlier time to a later time.
Again, congrats on a job well done!
