correct |dw:1443240965484:dw|

then we take 1/4th of that distance 6.3/4 = ??

1.575 which would round to 1.58

ok use this one http://web2.0calc.com/

u should use one but its not that hard i could do it using long division
anonymous
  • anonymous
USE long division and sorry if I sound mean I have no intention of sounding rude at all

I don't think the correct way to find the answer is using the 6.3. All of the possible answers you are giving me are not options. Its just like your walking from point a to point b in this case its 2.2 and 8.5. What Point are you at when you stop one-fourth of the way? Could that work?

that's exactly where my line of reasoning was heading Helpppmeee1999

Oh good!
jim_thompson5910
  • jim_thompson5910
take 1/4th of 6.3 then add that result to 2.2
anonymous
  • anonymous
4.3 maybe? My math isn't very good.
jim_thompson5910
  • jim_thompson5910
taking 1/4th of 6.3 is the same as dividing 6.3 over 4 when you used that calculator, what is the result of 6.3/4 ?
anonymous
  • anonymous
1.575
anonymous
  • anonymous
If you add 2.2 to that. Then my answer was correct.
anonymous
  • anonymous
My first answer.

jim_thompson5910
  • jim_thompson5910
yeah then you compute 2.2+1.575
anonymous
  • anonymous
So it is 3.775?
RagingSquirrel
  • RagingSquirrel
Yes

1/4 distance from a to b \[a+\frac{b-a}{4}=\frac{4a}{4}+\frac{b-a}{4}=\frac{4a+b-a}{4}=\frac{3a+b}{4}\] so you can just use a weighted mean. \[\frac{3\times2.2+8.5}{4}=3.775\]

Good planning Jim. Say that its incorrect, so I do all the work and get the answer myself. LOL
