$5\% \times 245$

• Use a definição $\color{green} {{  }}x\% = \frac{x}{100}$

$\frac{5}{100} \times 245$

• Divida-os por 5 $\color{green} {{  \frac{5 \div 5}{100 \div 5} = \frac{1}{20} }}$

$\frac{1}{20} \times 245$

• $\color{green} {{  }} \frac{1}{\cancel{ 20 } \div 5} \times \cancel{ 245 } \div 5= \frac{1}{4} \times 49$

$\frac{1}{4} \times 49$

$\frac{1}{4} \times \frac{49}{1}$

$\frac{1 \times 49}{4 \times 1}$

Resposta: $\color{green} \boxed{{  \frac{49}{4} }}$
