A

3. blackfireskull

A: 19/39

4. anonymous

can ya Explain how ya got the answer ?

5. anonymous

because 3 + 12 +17 + 7 = 39, so 12+7 = 19.

6. anonymous

ahh thanks

7. anonymous

the bottom number of the fraction (39) is added by all of the numbers combined.

8. anonymous

both of ya :)

9. anonymous

and the top of the fraction (19) is the numbers of the colors (Orange and green) (12 and 7)

10. anonymous

11. anonymous

14. anonymous

$-1\frac{ 5 }{ 6 } + -\frac{ 6 }{ 5 } = ?$

15. anonymous

16. anonymous

= 61/30

20. anonymous

21. anonymous

Ah, okay.

22. anonymous

So, we know it isn't A.

23. anonymous

lets move on to B

24. anonymous

yup

25. anonymous

so..

26. anonymous

$-1\frac{ 5 }{ 6 } + -\frac{ 5 }{ 6 }$ =?

27. anonymous
