Answer:


(-17)/(30)

Explanation:

Fine a common denominator. Both 5 and 6 will evenly go into 30 so make equivalent fractions with 30 as the denominator:


(-7)/(5) =
(-42)/(30) 5 x 6 is 30 so we multiply -7 x 6 to get -42


(5)/(6) =
(25)/(30) 6 x 5 is 30 so we multiply 5 x 5 to get 25


(-42)/(30) +
(25)/(30) =
(-17)/(30) The denominator stays the same 30. We add the numerators. -42 + 25 You add the absolute vales and take the sign of the larger absolute value. Absolute value is a positive number that shows the distance that number is from zero.
