Okay. This is the equation, right?:\[3w=4\frac{ 1 }{ 5 }\]
OpenStudy (anonymous):
yup
OpenStudy (kewlgeek555):
e.e
OpenStudy (kewlgeek555):
Okay. So it has a simple start. What equals four and one half? Put it in decimal form. This is easy. Do you know how to do this @reyna78724 ?
OpenStudy (nirmalnema):
3w=21/5
w=21/15
w=7/5

Yeah that's it
OpenStudy (kewlgeek555):
Hm...it seems that @nirmalnema got a slightly different answer than I did. I might have done something wrong or he/she might have done something wrong.
OpenStudy (kewlgeek555):
I don't know. I know that I know that 4 and one half is 4.5. That made the equation 3w = 4.5. Now you have to divide. 4.5 divided by 3 is 1.5. Now, @nirmalnema got 1.4...Hmm.
OpenStudy (nirmalnema):
@kewlgeek555 21/ 5 is = 4.2 not 4.5
OpenStudy (kewlgeek555):
21? Where did you get 21 from?
