• Use a definição [tex]\color{green} {{ }}x\% = \frac{x}{100} [/tex]
[tex] \frac{5}{100} \times 245 [/tex]
• Divida-os por 5 [tex]\color{green} {{ \frac{5 \div 5}{100 \div 5} = \frac{1}{20} }}[/tex]
[tex] \frac{1}{20} \times 245[/tex]
• [tex]\color{green} {{ }} \frac{1}{\cancel{ 20 } \div 5} \times \cancel{ 245 } \div 5= \frac{1}{4} \times 49[/tex]
[tex] \frac{1}{4} \times 49[/tex]
[tex] \frac{1}{4} \times \frac{49}{1} [/tex]
[tex] \frac{1 \times 49}{4 \times 1} [/tex]
Resposta: [tex]\color{green} \boxed{{ \frac{49}{4} }}[/tex]
