1.1 To convert 3.3 oz of butter to grams, use the conversion factor where 1 oz = 28.35 g. Therefore, \( 3.3 \text{ oz} \times 28.35 \text{ g/oz} = 93.585 \text{ g} \). Rounding to the nearest 5 grams gives us approximately **95 g** of butter. 1.2 For \( 1 \frac{1}{4} \) cups of milk, we first convert it to the decimal: \( 1 \frac{1}{4} \text{ cups} = 1.25 \text{ cups} \). Since 1 cup = 250 ml, we calculate: \( 1.25 \text{ cups} \times 250 \text{ ml/cup} = 312.5 \text{ ml} \). Rounding to the nearest 10 ml, we get approximately **310 ml**. 1.3 Mampho needs to make 108 squares of fudge. The original recipe makes 54 squares and requires 5 ml of vanilla essence. To find the amount of vanilla for 108 squares, we set up a proportion: \( \frac{108 \text{ squares}}{54 \text{ squares}} = 2 \). Therefore, she needs \( 2 \times 5 \text{ ml} = 10 \text{ ml} \) of vanilla essence, not 2 ml. Mampho is **not correct**. 1.4 To convert \( 200 \,^{\circ} \mathrm{F} \) to Celsius, use the formula: \( ^\circ \mathrm{C} = \left(200 - 32\right) \div 1.8 \). Calculating that gives: \( ^\circ \mathrm{C} = 168 \div 1.8 \approx 93.33 \,^{\circ} \mathrm{C} \). Therefore, the temperature in Celsius is about **93.3 degrees Celsius**. 1.5 If Mampho starts at 13:34 and the estimated time to make the fudge is 47 minutes, we add: 13:34 + 0:47 = 14:21. She needs to be finished by 14:15. Thus, Mampho will unfortunately be **finished late** at 14:21!
