To determine whose cake is less sweet, we can compare the ratio of sugar to flour in each recipe.
For Ronald's cake:
- Sugar: 2 cups
- Flour: 5 cups
The ratio of sugar to flour for Ronald's cake is: \[ \text{Ratio} = \frac{\text{Sugar}}{\text{Flour}} = \frac{2}{5} = 0.4 \]
For Madelyn's cake:
- Sugar: 6 cups
- Flour: 16 cups
The ratio of sugar to flour for Madelyn's cake is: \[ \text{Ratio} = \frac{\text{Sugar}}{\text{Flour}} = \frac{6}{16} = \frac{3}{8} = 0.375 \]
Now we can compare the two ratios:
- Ronald's ratio: 0.4
- Madelyn's ratio: 0.375
Since 0.4 > 0.375, this means Ronald's cake has a higher ratio of sugar to flour and is therefore sweeter than Madelyn's cake.
Thus, the answer is:
B. Madelyn's cake is less sweet.
