To find out how much sugar Lucy used to make one brownie, we need to divide the total amount of sugar used by the number of brownies made.

Given:
- Total amount of sugar used = $$ \frac{8}{5} $$ cups
- Number of brownies made = 24

Let's calculate the amount of sugar used per brownie:

$$ \text{Sugar used per brownie} = \frac{\text{Total amount of sugar used}}{\text{Number of brownies made}} $$

$$ \text{Sugar used per brownie} = \frac{\frac{8}{5}}{24} $$

Now, let's calculate the amount of sugar used per brownie.
Calculate the value by following steps:
- step0: Calculate:
  $$\frac{\frac{8}{5}}{24}$$
- step1: Multiply by the reciprocal:
  $$\frac{8}{5}\times \frac{1}{24}$$
- step2: Reduce the numbers:
  $$\frac{1}{5}\times \frac{1}{3}$$
- step3: Multiply the fractions:
  $$\frac{1}{5\times 3}$$
- step4: Multiply:
  $$\frac{1}{15}$$
The amount of sugar Lucy used to make one brownie is $$ \frac{1}{15} $$ cups or approximately 0.0667 cups.
Lucy used $$ \frac{1}{15} $$ cups of sugar to make one brownie.
