80%

Solution:

Concept:

The square root of a percentage is found by converting the percentage to a fraction, taking the square root, and then converting the result back to a percentage.

Explanation:

Write

64\%

as a fraction.

64\% = \frac{64}{100}

Take the square root of both numerator and denominator.

\sqrt{\frac{64}{100}} = \frac{\sqrt{64}}{\sqrt{100}}

\sqrt{64} = 8

and

\sqrt{100} = 10

So,

\sqrt{64\%} = \frac{8}{10} = 0.8

Convert

0.8

into a percentage.

0.8 = \frac{8}{10} = \frac{80}{100} = 80\%

Therefore, the square root of

64\%

80\%

Answer:

80\%
