To find the percent of decrease from 6 to 0, we can use the formula for percent decrease:
\[ \text{Percent Decrease} = \left(\frac{\text{Old Value} - \text{New Value}}{\text{Old Value}}\right) \times 100 \]
In this case:
- Old Value = 6
- New Value = 0
Substituting these values into the formula gives:
\[ \text{Percent Decrease} = \left(\frac{6 - 0}{6}\right) \times 100 = \left(\frac{6}{6}\right) \times 100 = 1 \times 100 = 100% \]
Therefore, the percent of decrease from 6 to 0 is 100%.
