Answer:

Exact Form: -53/12

decimal form: -4.416

mixed number -4 5/12

Step-by-step explanation:

convert mixed numbers into improper fractions: -2 3/3 +(5 1/2)+ 8 3/4

convert mixed numbers into improper fractions: =11/2 = $-\frac{23}{3}+\left(-\frac{11}{2}\right)+\frac{35}{4}$ =

$-\frac{23}{3}+\left-\frac{11}{2}\right+\frac{35}{4}$ $=-\frac{92}{12}-\frac{66}{12}+\frac{105}{12}$

$\frac{-92-66+105}{12}$

add/subtract the numbers: -92-66+105=-53

-53/12

apply the fraction rule: $\frac{-a}{b} = -\frac{a}{b\\}$

$=-\frac{53}{12}\\$
