Denominator is 5, so we can easily convert it into decimal by multiplying denominator and numerator by 2.

\(\displaystyle{\frac{{{3}}}{{{5}}}}={\frac{{{3}\times{2}}}{{{5}\times{2}}}}={\frac{{{6}}}{{{10}}}}={0.6}\)

To convert it to percent we have to multiply it by 100%

\(\displaystyle{0.6}\times{100}\%={60}\%\)

\(\displaystyle{\frac{{{3}}}{{{5}}}}={\frac{{{3}\times{2}}}{{{5}\times{2}}}}={\frac{{{6}}}{{{10}}}}={0.6}\)
