To find the percent of decrease from 8 to 6, you can use the formula:
\[ \text{Percent Decrease} = \frac{\text{Initial Value} - \text{Final Value}}{\text{Initial Value}} \times 100 \]
In this case, the initial value is 8 and the final value is 6. Plugging in these values:
\[ \text{Percent Decrease} = \frac{8 - 6}{8} \times 100 \]
Calculating the numerator:
\[ 8 - 6 = 2 \]
Now, substitute this back into the formula:
\[ \text{Percent Decrease} = \frac{2}{8} \times 100 \]
Simplifying \(\frac{2}{8}\):
\[ \frac{2}{8} = \frac{1}{4} \]
Now, converting \(\frac{1}{4}\) to a percentage:
\[ \frac{1}{4} \times 100 = 25 \]
Thus, the percent of decrease from 8 to 6 is:
\[ \boxed{25%} \]
