2 question is second image

3 question is third image

The answer to the first one is

Exact Form : 13/3

Decimal Form : 4.3 repeated

Mixed Number Form : 4  1/3

The answer to the second one is

Exact Form :   -1/2

Decimal form :    -0.5

The answer to the third one is

Exact Form :  5/6

Decimal Form : 0.83 repeated

Step-by-step explanation:

Step by step for the first one :  you have to find the LCD and then combine them.

Step by step for the second one : You have to simplify the numerator so multiply 1 and 4 and then you get  -6 + 4/ -1 - (-5). Then add -6 and 4 then you get -2/ -1 - (-5). Then You simplify the denominator, so you multiply  -1 by  -5 and you get -2/ -1 + 5. Then you add -1 and 5, then you get -2/4. Then you reduce the expression by cancelling the common factors. Cancel the common factor of -2 and 4 and you get -1/2.

Step by step for the third one : You reduce the expression , if possible, by cancelling the common factors.
