Answer 3

#### Calculation: 2 - 4.5 + (-0.5) = -2/5 + 8/15 + 2 ⅓ + (-4 + 2/3) To solve this calculation, let's break it down step by step: Step 1: Simplify the expression on the left side of the equation. 2 - 4.5 + (-0.5) = -2.5 + (-0.5) = -3 Step 2: Simplify the expression on the right side of the equation. -2/5 + 8/15 + 2 ⅓ + (-4 + 2/3) To add fractions, we need to find a common denominator. The common denominator for 5 and 15 is 15. -2/5 + 8/15 = -6/15 + 8/15 = 2/15 Next, we need to convert the mixed number 2 ⅓ into an improper fraction. 2 ⅓ = (2 * 3 + 1) / 3 = 7/3 Now, let's add the fractions and the mixed number: 2/15 + 7/3 + (-4 + 2/3) To add fractions, we need to find a common denominator. The common denominator for 15 and 3 is 15. 2/15 + 7/3 = 2/15 + (7 * 5) / (3 * 5) = 2/15 + 35/15 = 37/15 Finally, let's simplify the expression: 37/15 + (-4 + 2/3) To add a whole number and a fraction, we need to convert the whole number into a fraction with the same denominator as the fraction. -4 + 2/3 = (-4 * 3 + 2) / 3 = (-12 + 2) / 3 = -10/3 Now, let's add the fractions: 37/15 + (-10/3) To add fractions, we need to find a common denominator. The common denominator for 15 and 3 is 15. 37/15 + (-10/3) = (37 * 3) / (15 * 3) + (-10 * 15) / (3 * 15) = 111/45 + (-150/45) = -39/45 Step 3: Simplify the expression on the right side of the equation. -39/45 = -13/15 #### Answer: The solution to the equation 2 - 4.5 + (-0.5) = -2/5 + 8/15 + 2 ⅓ + (-4 + 2/3) is **-13/15**.
