what is - 12 3/14 + 5 5/7? my teacher taught us ti regroup, but thats with subtraction? apparently the answer is - 6 1/2 but what would you do to get there?

-6 1/2

Step-by-step explanation:

First, make - 12 3/14 an improper fraction!

1) - 12 3/14

2) - 171/14

Now make 5 5/7 an improper fraction!

1) 5 5/7

2) 40/7

Now find a common denominator for both fractions! (14)

1) - 171/14 <- - Already has the common denominator

2) 40/7

3) 80/14 <- - Now has 14 as denominator

Now add the two values together!

1) - 171/14 + 80/14

2) - 91/14

Now simplify the fraction - 91/14!

1) - 91/14

2) - 6 1/2
