Here are the solutions to the problems. c) Step 1: Rewrite the expression by removing the parentheses. (0.5) + (-0.25) + (-0.2) = 0.5 - 0.25 - 0.2 Step 2: Perform the subtraction from left to right. 0.5 - 0.25 = 0.25 Step 3: Perform the final subtraction. 0.25 - 0.2 = 0.05 The solution is 0.05. d) Step 1: Perform the first division from left to right. Dividing by a fraction is equivalent to multiplying by its reciprocal. (200) ÷ ((1)/(4)) = 200 × 4 = 800 Step 2: Perform the second division with the result from Step 1. 800 ÷ (0.2) Step 3: Convert the decimal to a fraction or perform the division directly. 800 ÷ 0.2 = 800 ÷ (2)/(10) = 800 ÷ (1)/(5) = 800 × 5 = 4000 The solution is 4000. 3 done, 2 left today.
