1. The problem is to find the difference between 7 3/8 % and 6 7/8 %. 2. First, convert the mixed percentages to improper fractions or decimals for easier subtraction. - 7 3/8 % = 7 + \frac{3}{8} = \frac{56}{8} + \frac{3}{8} = \frac{59}{8} = 7.375% - 6 7/8 % = 6 + \frac{7}{8} = \frac{48}{8} + \frac{7}{8} = \frac{55}{8} = 6.875% 3. Subtract the two percentages: $$7.375\% - 6.875\% = 0.5\%$$ 4. Therefore, the difference is 0.5%.
