Question

Puteti va rog se rezolvati acest calcul?$\frac{3}{16} : (0,75- \frac{1}{2})^{2} =?$

Answer 1

[tex]\frac{3}{16}:(0,75-\frac{1}{2})^2=\\ \frac{3}{16}:(\frac{3}{4}-\frac{1}{2})^2=\\ \frac{3}{16}:(\frac{1}{4})^2=\\ \frac{3}{16}:\frac{1}{16}=\\ \frac{3}{16}*16=3[/tex]

Answer 2

$\frac{3}{16} : ( 0 , 75 - \frac{1}{2} )^{2}$

Ridicam la putere ;


$\frac{3}{16} : ( 0 , 56 ) - \frac{2}{4} )$

Aducem la acelasi numitor fiind 4 pe primi ii inmultim cu 4 ;


$\frac{3}{16} : ( 2 , 24 - 2 )$

Facem scaderea din paranteza ;


$\frac{3}{16} : 0 , 24$

Impartirea devine inmultire prima fractie inmultita cu rasturnata .


$\frac{3}{16} * \frac{1}{0 , 24}$

$\frac{3}{3 , 84}$

0 , 78
