2.5% of what number is 2.21?

OpenStudy (timmyk14):

5.525

OpenStudy (timmyk14):

2.5x = 2.21 multiply both sides by 2.5.

OpenStudy (anonymous):

translate directly in to math \(2.5\%\) means \(0.025\) "of" means \(\times\) "what number" is what you are trying to find, i'll call it \(n\) "is" means \(=\) 2.21 is the number 2.21 you get \[.025\times n=2.21\]

OpenStudy (anonymous):

solve via \[n=2.21\div .025\]which is certainly not the answer you got above

OpenStudy (timmyk14):

OpenStudy (anonymous):
