Question

quanto é
3/8 dividido por 3/4

3/8 x 7/8
rais quadrada de 64
9

Answer 1

$\frac{3}{8} : \frac{3}{4} = \frac{3 . 4}{8 . 3} = \frac{12}{24} = \frac{1}{2}$

 $\frac{3}{3} . \frac{7}{8} = \frac{21}{24} = \frac{7}{8}$

$\sqrt{64} = 8$ 

$\sqrt{9} =3$       se for $\sqrt{ \frac{64}{9} } = \frac{8}{3}$

Answer 2

3 : 3 =  3 . 4 = 12  (:12) = 1
8   4     8   3     24 (:12)    2

3 . 7 = 21
8   8    64

√64 = 8
√9 =  3

√64  = 8
√9       3
