1.1 Step 1: Calculate the batter volume for the given recipe. Water = 250 ml 1 cup sugar = 250 ml Oil = 125 ml Total volume = 250 + 250 + 125 = 625 ml Step 2: Set up the proportion for flour. 250 g flour625 ml batter = x g flour750 ml batter x = 250 × (750)/(625) (750)/(625) = 1.2 x = 250 × 1.2 = 300 Rose uses 300 g flour. 300 g 1.2 Step 1: Calculate the number of 100 g units in 300 g flour. 300 g100 g/unit = 3 units Step 2: Calculate the cost. Cost = 3 × R17 = R51 The cost is R51. R51 1.3 Step 1: Calculate the temperature increase. Increase = 15\% of 180^C 0.15 × 180 = 27^ Step 2: Calculate the new temperature. New temperature = 180^ + 27^ = 207^ The new temperature is 207^C. 207^ C 1.4 (assuming recommended time of 45 min as per standard recipe instruction) Step 1: Set up the percentage formula. Percentage = ( 35 min45 min ) × 100\% Step 2: Simplify the fraction. (35)/(45) = (7)/(9) Step 3: Calculate the percentage. (7)/(9) × 100 = (700)/(9) ≈ 77.78\% (or exactly (700)/(9)\%) The cake was baked at 77.78\% of the recommended time. 77.78\% 2.1 The recipe is for 1 large cake. Three small cakes together are equivalent to 1 large cake. Total sugar used = 1 cup. 1 cup 1 cup 2.2 Similarly, total flour used for three small cakes = 250 g. 250 g 250 g
