anonymous one year ago Which rational number is one-half of the way between 2 and 6.5?

1. zepdrix

Do you know how to find the distance between 2 and 6.5? :)

2. anonymous

4.75 2.25 4.25 4.5

3. anonymous

4.5 would be the answer to me?

4. zepdrix

4.5 is the space between 2 and 6.5, the full distance :) good. They want half of that.

5. anonymous

2.25

6. zepdrix

yay good job \c:/

7. zepdrix

oh oh oh wait wait im being stupid :O

8. anonymous

:o

9. anonymous

and I thought "Of wow thats simple.." lol

So you found half of the distance between 2 and 6.5. Good 2.25. We started at 2 though. So you need to add 2.25 to your 2 to find the half-way point.

oh*

12. anonymous

4.25

13. zepdrix

|dw:1442365909194:dw|2.25 is clearly not the half-way point lol

14. zepdrix

yay good job \c:/

15. anonymous

yeah lol!

16. anonymous

so its 4.25?

An alternative is to add up the two numbers. Then divide by 2 $\Large \frac{2+6.5}{2}=\frac{8.5}{2} = 4.25$ and you get the same answer. The method zepdrix used is probably more intuitive though.

ahh average :) ya i like that better :D
