Question

sabendo que 30% de um número equivale a 60 determine esse número​

Answer 1

Resposta:

$\red{ \boxed{\Large{\bf{x = 200}}}}$

Explicação passo-a-passo:

$\Large\bf{30\% \times x = 60}$

$\Large\bf{ \frac{30}{100}x = 60 }$

$\Large\bf{ \frac{ \cancel{30}}{ \cancel{100}}x = 60 }$

$\Large\bf{ \frac{3}{10} } x = 60$

$\Large\bf{ \frac{10}{3} \times \frac{3}{10}x = \frac{10}{3} \times 60 }$

$\Large\bf{ \frac{ \cancel{10}}{ \cancel{3}} \times \frac{ \cancel{3}}{ \cancel{10}} \: x = \frac{10}{ \cancel{3}} \times \cancel{60}}$

$\Large\bf{ \frac{1}{3} \times 3x = \frac{10}{3} \times 60}$

$\Large\bf{x = \frac{10}{3} \times 60}$

$\Large\bf{x = 10 \times 20}$

$\red{ \boxed{\Large{\bf{x = 200}}}}$
