## anonymous one year ago Medal Picture below I got two different answers

1. anonymous

2. anonymous

-y-40/8 and -40=y

3. johnweldon1993

Well... $\large 5 - \frac{y}{8} = \frac{8}{8} \times 5 - \frac{y}{8} = \frac{40}{8} - \frac{y}{8} = \frac{40 - y}{8}$ I actually don't think either are correct there hun :/ But do you see what I did?

4. johnweldon1993

Find the common denominator first...then carry out the subtraction

5. anonymous

I did the same thing in my first one but thought it was negative,

6. johnweldon1993

Nope...that '5' never becomes negative to begin with...the common denominator is 8...so after you multiply the 5 by 8/8 you get that 40/8 term...but no negative :)

7. anonymous

Yeah I understand. thank you.

8. johnweldon1993

No problem!

9. anonymous

Is this the same is the one above ? -6+5/6

10. johnweldon1993

Well yes and no...you'll actually be able to carry out the addition this time

11. anonymous

so the mixed number would be the answer?

12. johnweldon1993

Hmm, theoretically yes...but I hardly ever see a software or a teacher wanting a mixed number as the answer...probably just leave it as an improper fraction $\large -\frac{31}{6}$ if my quick mental math is right

13. anonymous

yeah i made it into -5 1/6

14. johnweldon1993

Well either way yes it is correct :)
