REGRA DE TRÊS​

Answer 1

Resposta:

a) 9,09%

b) 35,45%

c) 27,27%

d) 18,18%

Explicação passo-a-passo:

a) 100% * 1 = 11 * x

100% = 11x

100%/11 = x

x = 9,09 %

b) 100% * 5 = 11 * x

500% = 11x

500%/11 = x

x = 45,45 %

c) 100% * 3 = 11 * x

300% = 11x

300%/11 = x

x = 27,27 %

d) 100% * 2 = 11 * x

200% = 11x

200%/11 = x

x = 18,18 %
