Sounds like you're adding and subtracting fractions.
-4/7 - -6/7
Whenever you're subtracting add the opposite. So here we're subtracting a negative, so we'll add a positive
Rewrite like this:
-4/7 + 6/7
Because we already have common denominators go ahead and add the numerators.
What's -4 + 6?
Your answer is 2/7.
Hope that helped...Good Luck in your Math.

I believe you are asking -4/7 - (-6/7)
Since they have a common denominator already you just need to add the numerators : - 4 - (- 6) = -4 + 6 = 2
So your answer is -4/7 + 6/7 = 2/7

Ok let me get this right...
Is this problem???...
(-4/7) - (-6/7)=?
Is that right?
If so then....
Since the denominators (bottom numbers of the fractions) are the same...
you can combind the problem....so you get...
((-4)-(-6))/7
....Since a negative times a negative makes a positive....
(-4+6)/7
or re-write it as...
(6-4)/7
...so you just do basic subtraction...
and you get....
2/7...
or if you want it in decimal point...

Hopefully I answered your question...
If not just tell me
