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 =[tex]-\frac{23}{3}+\left(-\frac{11}{2}\right)+\frac{35}{4}[/tex] =
[tex]-\frac{23}{3}+\left-\frac{11}{2}\right+\frac{35}{4}[/tex][tex]=-\frac{92}{12}-\frac{66}{12}+\frac{105}{12}[/tex]
[tex]\frac{-92-66+105}{12}[/tex]
add/subtract the numbers: -92-66+105=-53
-53/12
apply the fraction rule: [tex]\frac{-a}{b} = -\frac{a}{b\\}[/tex]
[tex]=-\frac{53}{12}\\[/tex]
