Question

Calcule x sabendo que: 0,06/0,25=0,18/x

Answer 1

$\frac{0,06}{0,25}=0,18x\\\frac{100}{100}\cdot \frac{0,06}{0,25}=0,18x\\\frac{6}{25}=0,18x\\x=\frac{6}{25\cdot 0,18}\\x=\frac{6}{25\cdot 0,18}\cdot \frac{100}{100}\\x=\frac{6\cdot 100}{25\cdot 18}\\x=\frac{100}{25\cdot 3}\\\boxed{\bold{x=\frac{4}{3}\:ou\:0,75}}$
