Answer:
-4(11)/(15)

Explanation:

Problem:
2+(2)/(3)+(3)/(5)-8

1. Add the whole numbers first


-6+(2)/(3) +(3)/(5)

2. Find the Least Common Denominator (LCD)

LCD = 15

3. Make the denominators the same as the LCD


-6*(15)/(15) +(2*5)/(3*5) +(3*3)/(3*3)

4. Simplify.


-(90)/(15)+(10)/(15) +(9)/(15)

5. Join the denominators


(-90+10+9)/(15)

6. Simplify


-(71)/(15)

7. Convert to mixed fractions


-4(11)/(15)
