Answer 1

$\boxed{\boxed{x\%=\frac{x}{100}}}$

$48\%=\frac{48}{100}\\\\48\%=\frac{48\div4}{100\div4}\\\\48\%=\frac{12}{25}$
_________________________

$140\%=\frac{140}{100}\\\\140\%=\frac{14}{10}\\\\140\%=\frac{14\div2}{10\div2}\\\\140\%=\frac{7}{5}$
_________________________

$80\%=\frac{80}{100}\\\\80\%=\frac{8}{10}\\\\80\%=\frac{8\div2}{10\div2}\\\\80\%=\frac{4}{5}$
