Answer:
31/40
Step-by-step explanation:
Given expression:

Note: Both fractions must have same denominators if we want to perform addition, subtraction, multiplication, or division.
The only way to simplify this expression is to have a common denominator, which can be determined by the LCM of 5 and 8.
- ⇒ Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45...
- ⇒ Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72...
Multiply the denominators with such a number that is equivalent to 40.
Note: The number you are multiplying should also be multiplied to the numerator.


Finally, simplify the expression to determine the solution.

Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.

Answer:
-1625
Step-by-step explanation:
→ (-125) × 5 + (-125) × 8
