Khan Academy

Supporting grades: 6

Description: This word problem is expressed simply, which can be confusing to some. Take your time and focus on the what is being asked for. Created by Sal Khan and Monterey Institute for Technology and Education. These problems tend to kill people because on some level they're kind of simple, they're just 100 and an 80 there, and they're asking what percent. They're saying that this value right here, this 100, is some percentage of 80, and that some percentage is what we have to figure out. So if we multiply 80 by this what percent, we will get 100.
