To calculate the percent change from 5 to 6, you can use the following formula:
\[ \text{Percent Change} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]
In this case, the old value is 5, and the new value is 6. Plugging in these values:
\[ \text{Percent Change} = \left( \frac{6 - 5}{5} \right) \times 100 \]
\[ = \left( \frac{1}{5} \right) \times 100 \]
\[ = 0.2 \times 100 \]
\[ = 20% \]
Thus, the percent change from 5 to 6 is 20%.
