Cálculo de percentual&nbsp;
inverso.

Utilizaremos este cálculo sempre que tivermos dois números e
precisarmos&nbsp; saber quanto um representa
em termos percentuais em relação ao outro .

Por exemplo :

10&nbsp; e&nbsp; 100

Sabemos &nbsp;&nbsp;sem
dúvida&nbsp; alguma e sem precisar calcular
que 10 é 10% de 100 .

Porém se tivermos 

2,95&nbsp; e 3,25 já fica
complicado saber só olhando.

Contudo é muito simples&nbsp;
e fácil calcular isso, basta dividir o número menor pelo número maior e
multiplicar por 100, assim:

2,95 / 3.25 = 0,90769 x 100 = 90.7692308 , arredondando&nbsp; 90,77%

Dica para nunca mais esquecer :&nbsp;&nbsp; Estranhamente divide-se o número menor pelo
maior depois&nbsp; multiplica-se por 100.
