(3) Lucy uses \( \frac{8}{5} \) cups of sugar to make 24 brownies. How much sugar did she use to make one brownie?

To determine how much sugar Lucy uses for one brownie, we’ll divide the total amount of sugar by the number of brownies made. She uses \( \frac{8}{5} \) cups of sugar for 24 brownies. So, we calculate: \[ \text{Sugar per brownie} = \frac{\frac{8}{5}}{24} = \frac{8}{5} \times \frac{1}{24} = \frac{8}{120} = \frac{1}{15} \] Thus, Lucy uses \( \frac{1}{15} \) cups of sugar for each brownie. Now, isn’t it fascinating how small fractions can play a big role in baking? Sharing recipes and adjusting them often involves similar calculations, making cooking both an art and a science!
