Question

Add or subtract as indicated.
- 7/5 + 5/6

Answer 1

`(-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.
