Answer 2

Explicação passo-a-passo:

A)

$\dfrac{15}{45} \div \dfrac{15}{15}$

$\dfrac{15}{45} \times \dfrac{15}{15}$

$\dfrac{225 {}^{ \div 225} }{725 {}^{ \div 225} }$

=>1/3

B)

$\dfrac{16}{24}$

$\dfrac{16 {}^{ \div 8} }{24 {}^{ \div 3} }$

=>2/3

C)

$\dfrac{25}{100}$

$\dfrac{25 {}^{ \div 25} }{100 {}^{ \div 25} }$

=>1/4

D)

$\dfrac{16}{40}$

$\dfrac{16 {}^{ \div 8} }{40 {}^{ \div 8} }$

=>2/5
