Question

Quantos % equivale o valor 75,00 $ de 125,50 $ ?

Answer 1

R$ 125,50 = 100%

R$ 75,00 = x

Multiplicando em X (ou em cruz), temos que 125,50 . x = 75 . 100

Portanto, x = $\frac{75 . 100}{125,50$

x = 59,7%

Answer 2

$125,50 \to 100\%\\75,00\;\;\;\;\;\;\;\to \;\;x \\\\\qquad \Rightarrow x = \frac{75,00\times 100}{125,50}\\\\\Rightarrow x = \frac{7500\times 100}{12550}\\\\\Rightarrow x = \frac{750\times 100}{1255}\\\\\Rightarrow x = \frac{75000}{1255}\\\\\Rightarrow x = 59,8\%$
