The movement of the progress bar may be uneven because questions can be worth more or less (including zero) depe Subtract $8 \frac{1}{5}-4 \frac{2}{5}$. Simplify the answer and write as a mixed number. $3 \frac{1}{5}$ $4 \frac{1}{5}$ $4 \frac{4}{5}$ $3 \frac{4}{5}$

Step 1 ：Subtract the whole numbers: 8 - 4 = 4

Step 2 ：Subtract the fractions: \(\frac{1}{5} - \frac{2}{5} = -\frac{1}{5}\)

Step 3 ：Since the fraction in the minuend is smaller than the fraction in the subtrahend, borrow 1 from the whole number part of the minuend and add it to the fraction part of the minuend: 4 - 1 = 3 and \(-\frac{1}{5} + 1 = \frac{4}{5}\)

Step 4 ：Final Answer: \(\boxed{3 \frac{4}{5}}\)
