Final answer:
The value of (-6 1/3) + (-3 2/5) is -146/15.
Step-by-step explanation:
To find the value of (-6 1/3) + (-3 2/5), we need to convert the mixed numbers to improper fractions. (-6 1/3) is equivalent to -19/3 and (-3 2/5) is equivalent to -17/5.
Next, we add the fractions by finding a common denominator. The least common multiple of 3 and 5 is 15. So, we multiply -19/3 by 5/5 to get -95/15, and we multiply -17/5 by 3/3 to get -51/15.
Finally, we add -95/15 and -51/15 to get -146/15. Therefore, the value of (-6 1/3) + (-3 2/5) is -146/15.
