answer : -2 1/3 - (-5) =
2(2)/(3)

explanation : we need to convert the mixed numbers to improper fractions, then find the LCD and combine.

step 1 : convert the mixed number to an improper fraction

ex:
-(7)/(3)-(-5)

step 2 : when there is a - in front of an expression in parentheses, change the sign of each term in the expression

ex :
-(7)/(3)+5

step 3 : calculate the sum

ex :
(8)/(3)

solution :
(8)/(3)

simplify:
2(2)/(3)

exact form :
(8)/(3)

decimal form : 2.66666666 (repeating)

mixed number form :
2(2)/(3)

hope this helps !
