    \[ now change division to multiplication you can divide 1 over 1 =1

    Yes, you get 1/25 if the book says otherwise, it is a mistake.

    \[ \huge\rm \frac{ \frac{ 1 }{ 1 } }{ \frac{ 1 }{ 25 } } =\frac{ 1 }{ \frac{ 1 }{ 25 }} \] that is true but the question starts with \[ \frac{ \frac{ 1 }{ 1 } }{ \frac{ 1 }{ 5^{-2} } }\]

    \[\frac{ \frac{ 1 }{ 1} }{ \frac{ 1 }{ 5^{-2} }} = \frac{ \frac{ 1 }{ 1 } }{ \frac{ 5^2 }{ 1 } }\] flip the fraction to get positive exponent

    yes then 1/25 is right you must need to flip the denominator fraction

    \(\color{blue}{\text{Originally Posted by}}\) @Nnesha \[\frac{ \frac{ 1 }{ 1} }{ \frac{ 1 }{ 5^{-2} }} = \frac{ \frac{ 1 }{ 1 } }{ \frac{ 5^2 }{ 1 } }\] flip the fraction to get positive exponent \(\color{blue}{\text{End of Quote}}\) this is right then
