Cameron used 1 3/4 ounces of hydrochloric acid in one experiment. She used 2 1/8 ounces of acid in a second experiment. How much more acid did she use in the second experiment

To determine how much more acid Cameron used in the second experiment compared to the first, we'll subtract the amount of acid used in the first experiment from the amount used in the second experiment.

1. **Amounts given:**
   - First experiment: \(1 \frac{3}{4}\) ounces
   - Second experiment: \(2 \frac{1}{8}\) ounces

2. **Convert the mixed numbers to improper fractions:**
   - \(1 \frac{3}{4}\) = \(\frac{7}{4}\) (since \(1 \times 4 + 3 = 7\))
   - \(2 \frac{1}{8}\) = \(\frac{17}{8}\) (since \(2 \times 8 + 1 = 17\))

3. **Find a common denominator to subtract the fractions:**
   - The common denominator for 4 and 8 is 8.
   - Convert \(\frac{7}{4}\) to \(\frac{14}{8}\) (since \(7 \times 2 = 14\)).

4. **Subtract the fractions:**
   \[
   \frac{17}{8} - \frac{14}{8} = \frac{3}{8}
   \]

So, Cameron used \(\frac{3}{8}\) ounces more acid in the second experiment.
