Answer 1

A

Answer 2

tell me how you got it please?

Answer 3

-1/3= -4/12

3/4= 9/12

-4/12+9/12=5/12

Answer 4

get a common denominator first (3 times 4 = 12)

Answer 5

then multiply the numerators by what you did to the denominators (so -1 times 4 = -4) and (3 times 3 = 9)

Answer 6

so you have -4/12 and 9/12... add them... which equals 5/12

Answer 7

get the explanation?

Answer 8

\[{-1\over3} + {3\over4}={-1\over3}*{4\over4} + {3\over4}*{3\over3}={-4\over12}+{9\over12}={5\over12}\]
