Answer 1

Olá!

·FRAÇÃO...

A)

$6 \div \frac{4}{6} =$

$6 \times \frac{6}{4} = \frac{36 ^{ \div 4} }{4 ^{ \div 4} } = 9$

B)

$\frac{6}{20} \times \frac{9}{8} =$

$\frac{54 ^{ \div 2} }{160 ^{ \div 2} } = \frac{27}{80}$

C)

$\frac{2}{7} \times \frac{6}{5} =$

$\frac{12}{35}$

D)

$\frac{8}{9} \times \frac{2}{ 7} =$

$\frac{16}{63}$

·RAÍZ QUADRADA...

A)

$\sqrt{ \frac{9}{16} } =$

$\frac{ \sqrt{9} }{ \sqrt{16} } = \frac{3}{4}$

B)

$\sqrt{ \frac{1}{25} } =$

$\frac{ \sqrt{1} }{ \sqrt{25} } = \frac{1}{5}$

C)

$\sqrt{ \frac{9}{25} } =$

$\frac{ \sqrt{9} }{25} = \frac{3}{5}$

D)

$\sqrt{ \frac{16}{49} } =$

$\frac{ \sqrt{16} }{ \sqrt{49} } = \frac{4}{7}$
