Answer 1

Răspuns:

a) mai mic cu = scădere

$\frac{6}{10} - \frac{3}{10} = \frac{3}{10}$

$\frac{8}{10} - \frac{3}{10} = \frac{5}{10} = \frac{1}{2} (s - a \: putut \: simplifica \: cu \: 5)$

$\frac{9}{10} - \frac{3}{10} = \frac{6}{10} = \frac{3}{5}$

$\frac{10}{10} - \frac{3}{10} = \frac{7}{10}$

b) mai mari cu = adunare

$\frac{2}{9} + \frac{5}{9} = \frac{7}{9}$

$\frac{2}{9} + \frac{7}{9} = \frac{9}{9} = 1$

$\frac{2}{9} + \frac{3}{9} = \frac{5}{9}$

$\frac{2}{9} + \frac{6}{9} = \frac{8}{9}$

Bună !!

•Cerința :

~în atașament .

•Rezolvarea:

~mai jos.

$a) \: \frac{6}{10} - \frac{3}{10} = \frac{3}{10 } \\ \frac{8}{10} - \frac{3}{10} = \frac{5}{10}^{(5} = \frac{1}{2} \\ \frac{9}{10} - \frac{3}{10} = \frac{6}{10} ^{(2} = \frac{3}{5} \\ \frac{10}{10} - \frac{3}{10} = \frac{7}{10}$

$b) \: \frac{2}{9} + \frac{5}{9} = \frac{7}{9} \\ \frac{2}{9} + \frac{7}{9} = \frac{9}{9} = 1 \\ \frac{2}{9} + \frac{3}{9} = \frac{5}{9} \\ \frac{2}{9} + \frac{6}{9} = \frac{8}{9}$

^^Aceasta a fost rezolvarea exercițiului .^^

Sper sa fie de ajutor !!:)

***Succes la teme!!;)
