Best ResponseYou've already chosen the best response.2so you simply need to find 88% of 1000 to get the number of students that score 2 or higher

Best ResponseYou've already chosen the best response.20.088 students? haha are you planning to cut the students ? maybe forget the formulas. out of 100 students, if 88 students are good, then how many students will be good out of 1000 students ?

Best ResponseYou've already chosen the best response.0I could've multiplied it, but I didn't think of it, and bc if 100 = 88 and 100, 10 times is 1000 so I added 88 10 times..
