Answer 1

Olá

• Primeiro eu vou ensinar a fazer como faz ok?
• Usamos definição p% =
• $\LARGE{} \frac{p}{100}$
• Sabendo disso vamos lá

1. $\LARGE{} \frac{55}{100} \\ \\ \LARGE{}\cancel{ \frac{55}{100} } \div 5 \\ \\ \LARGE\boxed{ \frac{11}{20} }$
2. $\LARGE{} \frac{42}{100} \\ \\ \LARGE{}\cancel{ \frac{42}{100} } \div 2 \\ \\ \LARGE\boxed{ \frac{21}{50} }$
3. $\LARGE{} \frac{35}{100} \\ \\ \LARGE{}\cancel{ \frac{35}{100} } \div 5 \\ \\ \LARGE\boxed{ \frac{7}{20} }$
4. $\LARGE{} \frac{20}{100} \\ \\ \LARGE{}\cancel{ \frac{20}{100} } \div 20 \\ \\ \LARGE\boxed{ \frac{1}{5} }$
5. $\LARGE{} \frac{25}{100} \\ \\ \LARGE{}\cancel{ \frac{25}{100} } \div 25 \\ \\\LARGE{} \LARGE\boxed{ \frac{1}{4} }$
6. $\LARGE{} \frac{60}{100} \\ \\ \LARGE{}\cancel{ \frac{60}{100} \div 20 } \\ \\ \LARGE\boxed{ \frac{3}{5} }$
7. $\LARGE{} \frac{85}{100} \\ \\ \LARGE{}\LARGE{}\cancel{ \frac{85}{100} } \div 5 \\ \\ \LARGE\boxed{ \frac{17}{20} }$
8. $\LARGE{} \frac{10}{100} \\ \\ \LARGE{}\cancel{ \frac{10}{100} } \div 10 \\ \\ \LARGE\boxed{ \frac{1}{10} }$
9. $\LARGE{} \frac{15}{100} \\ \\\LARGE{} \cancel{ \frac{15}{100} } \div 5 \\ \\ \LARGE\boxed{ \frac{3}{20} }$
10. $\LARGE{} \frac{18}{100} \\ \\ \LARGE{}\cancel{ \frac{18}{100} } \div 2 \\ \\ \LARGE\boxed{ \frac{9}{50} }$
