Salut :)
[tex]\bf 20 \: procente \: + 160 => \frac{20}{100} + \frac{160}{1}[/tex]
[tex]\bf \frac{20}{100} + \frac{160}{1} = \frac{1}{5} + \frac{160}{1} = \frac{1}{5} + \frac{800}{5} = \frac{800+1}{5} = \boxed{\frac{801}{5}} [/tex]
[tex]\bf 32 \: procente \: - 150 => \frac{32}{100} - \frac{150}{1} [/tex]
[tex]\bf \frac{32}{100} - \frac{150}{1} = \frac{8}{25} - \frac{150}{1} = \frac{8}{25} - \frac{3750}{25} = \frac{8-3750}{25} = \frac{-3742}{25} = \boxed{-\frac{3742}{25}} [/tex]
Succes :)
