    Given:

    \dfrac{1}{4}\text{ to }\dfrac{1}{2}

    To find:

    The percent of change, round to the nearest 10th of a percent.

    Solution:

    We have,

    Initial value = \dfrac{1}{4}

    New value = \dfrac{1}{2}

    We know that, the percentage change is

    \%\text{ change}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100

    Putting the given values, we get

    \%\text{ change}=\dfrac{\dfrac{1}{2}-\dfrac{1}{4}}{\dfrac{1}{4}}\times 100

    \%\text{ change}=\dfrac{\dfrac{2-1}{4}}{\dfrac{1}{4}}\times 100

    \%\text{ change}=\dfrac{\dfrac{1}{4}}{\dfrac{1}{4}}\times 100

    \%\text{ change}=1\times 100

    \%\text{ change}=100\%

    Here, the % change is positive, it represents the percent increase.

    Therefore, the percent of change is 100% of increase.
