Answer 2

To solve the expression, let's break it down step by step:

1. Simplify the multiplication: 3 1/5 × (-10) To multiply a mixed number by a whole number, we convert the mixed number to an improper fraction first: 3 1/5 = (5 × 3 + 1) / 5 = 16/5

Now we can multiply: 16/5 × (-10) = (16 × (-10)) / 5 = -160/5 = -32

2. Simplify the division: -4 : (-0.5) Dividing by a negative number is equivalent to multiplying by its reciprocal. The reciprocal of -0.5 is -2: -4 ÷ (-0.5) = -4 × (-2) = 8

3. Combine the results: -32 - 8 = -40

Therefore, 3 1/5 × (-10) - 4 : (-0.5) equals -40.
