8.75% --> 0.0875 as a decimal 0.0875x = 120 solve for x then 40% --> 0.4 as a decimal so 0.4x = ?

OpenStudy (rebeccapink6398):

???

jigglypuff314 (jigglypuff314):

"8.75% of a number is 120" 8.75% as a decimal = 0.0875 "of" means multiplication "a number" -> x "is" means "=" so you get 0.0875 times x = 120 solve for x

OpenStudy (rebeccapink6398):

????

jigglypuff314 (jigglypuff314):

OpenStudy (rebeccapink6398):

OpenStudy (the_fizicx99):

0.0875x = 120 Sove for x, you're still not done it's asking for 40% of that number

OpenStudy (rebeccapink6398):

jigglypuff314 (jigglypuff314):

^ yes I was taking it step by step x = 120 divided by 0.0875 which you would then multiply by 0.4

jigglypuff314 (jigglypuff314):

ohhhhh I miss read that as 8.75% not 75% okay then so x = 120 divided by 0.75 then multiply that by 0.4

OpenStudy (rebeccapink6398):
