To answer these questions, I will make some assumptions about the vetkoek recipe, as the full recipe details are not provided in the image. These assumptions are based on typical vetkoek recipes for one batch (assumed to yield 40 vetkoeks, as implied by question 1.7): Oil needed for one batch: 75 ml Yeast needed for one batch: 10 g Lukewarm water needed for one batch: 500 ml (0.5 L) Time components for one batch: Preparation/Mixing: 15 minutes First rise: 60 minutes Shaping: 10 minutes Frying: 15 minutes --- 1.4 Calculate how many full tablespoons of oil she will need for one batch. Step 1: Identify the total oil needed for one batch and the volume of one tablespoon. Oil needed for one batch = 75 ml Volume of one tablespoon = 15 ml Step 2: Divide the total oil needed by the volume of one tablespoon. Number of tablespoons = 75 ml15 ml/tablespoon Number of tablespoons = 5 Nomsa will need 5 full tablespoons of oil. 5 full tablespoons 1.5 Calculate the amount of yeast (in grams) Nomsa would need if she decided to only make 10 large vetkoeks. Step 1: Identify the yeast needed for one batch (40 vetkoeks). Yeast for 40 vetkoeks = 10 g Step 2: Calculate the amount of yeast needed per vetkoek. Yeast per vetkoek = 10 g40 vetkoeks = 0.25 g/vetkoek Step 3: Multiply the yeast per vetkoek by the desired number of vetkoeks (10). Yeast for 10 vetkoeks = 0.25 g/vetkoek × 10 vetkoeks = 2.5 g Nomsa would need 2.5 grams of yeast. 2.5 g 1.6 Nomsa wants to make 120 vetkoeks in total. Calculate how many litres of lukewarm water she will need for this order. Step 1: Determine the number of batches needed for 120 vetkoeks. One batch makes 40 vetkoeks. Number of batches = 120 vetkoeks40 vetkoeks/batch = 3 batches Step 2: Identify the lukewarm water needed for one batch. Water for one batch = 500 ml = 0.5 L Step 3: Multiply the water needed per batch by the number of batches. Total water needed = 0.5 L/batch × 3 batches = 1.5 L Nomsa will need 1.5 litres of lukewarm water. 1.5 L 1.7.1 Calculate the total time, in minutes, it takes to complete ONE batch. Step 1: Sum up all the time components for one batch. Total time = Preparation + First rise + Shaping + Frying Total time = 15 minutes + 60 minutes + 10 minutes + 15 minutes Total time = 100 minutes It takes 100 minutes to complete one batch. 100 minutes 1.7.2 Determine the latest time she should start her preparation to ensure the batch is ready at 11:00. Step 1: Convert the total time from minutes to hours and minutes. 100 minutes = 1 hour and 40 minutes Step 2: Subtract the total time from the desired finish time (11:00). 11:00 - 1 hour 40 minutes Subtracting 1 hour from 11:00 gives 10:00. Subtracting 40 minutes from 10:00 gives 09:20. The latest time she should start her preparation is 09:20. 09:20 Drop the next question.
