I need help adding negative fraction and positives?

so change -2 2/5 and 6 1/2 into improper fractions: -2 2/5 as an improper fraction is -8/5 and 6 1/2 as an improper fraction is 9/2.

so now you have -8/5+9/2.

now find a common denominator.

the common denominator is 10 so multiply both of them by a number that should make the denominator 10. you would multiply -8/5 by 2 and 9/2 by 5 so that both their denominators are 10. from there you should end up with: -16/10+45/10. then add that, which comes out to be 29/10 and you can change that to a mixed number if you want, which will be 2 9/10.

There are two ways to do this, so I'll show you both

1)Do the whole numbers first. -2 + 6 = 4

Now do the fractions. First you have to get them with the same denominator, and the lowest common denominator is 10

-2/5 + 1/2

= -4/10 + 5/10

= 1/10

now put it back together

4 1/10

2) Turn them into improper fractions

-2 2/5 + 6 1/2

-12/5 + 13/2

-24/10 + 65/10

41/10

4 1/10
