Então seria: 10 P=---- 20 Agora em porcentagem faríamos primeiro uma fração 10÷20 que vai ser igual a 0,5 que de fração para porcentagem representa (50%). Então pelos meus cálculos seria letra (d) Espero ter acertado ❤ OBS: não sou professora, sou uma aluna na qual tenho um bom desempenho em matemática.
