Answer 2

Let's break down each of these calculations step by step:

1. -5/9 - (-2/3): To subtract a negative number, you can change it to addition: -5/9 + 2/3 To add these fractions, you need a common denominator, which is 9. -5/9 + (2/3 * 3/3) = -5/9 + 6/9 Now, you can subtract them: (-5/9 + 6/9) = 1/9 So, -5/9 - (-2/3) = 1/9.

2. -3.07 * (-0.25): Multiply these two numbers: -3.07 * (-0.25) = 0.7675 So, -3.07 * (-0.25) = 0.7675.

3. -4 1/2 * (-1 1/3): First, convert the mixed numbers to improper fractions: -4 1/2 = -9/2 -1 1/3 = -4/3 Now, multiply these fractions: (-9/2) * (-4/3) To multiply fractions, multiply the numerators and denominators separately: (-9 * -4) / (2 * 3) = 36/6 Simplify the fraction: 36/6 = 6 So, -4 1/2 * (-1 1/3) = 6.

4. -2 1/3 * 0.125: First, convert the mixed number to an improper fraction: -2 1/3 = -7/3 Now, multiply this fraction by 0.125: (-7/3) * 0.125 = -0.291666667 (rounded to 9 decimal places) So, -2 1/3 * 0.125 is approximately equal to -0.291666667.
