How do i do percent problems? please help me i forgot how to do them

OpenStudy (anonymous):

what kind of percent problem?

OpenStudy (anonymous):

what number is 160 percent of 240?

OpenStudy (anonymous):

What I like to do is set up a proportion \[percent/100= value you want/whole value\]

OpenStudy (anonymous):

240 * 1.6

OpenStudy (anonymous):

so 160 would be your percent, 240 would be your whole value, and the value you want would be your x

OpenStudy (anonymous):

160/100=x/240

OpenStudy (anonymous):

cross multiply and solve for x

OpenStudy (anonymous):

240*160=x*100 38400=x*100 384=x

OpenStudy (anonymous):

384 is 160% of 240

OpenStudy (anonymous):

(160/100)*240 = 384
