a) mai mic cu = scădere
[tex] \frac{6}{10} - \frac{3}{10} = \frac{3}{10} [/tex]
[tex] \frac{8}{10} - \frac{3}{10} = \frac{5}{10} = \frac{1}{2} (s - a \: putut \: simplifica \: cu \: 5)[/tex]
[tex] \frac{9}{10} - \frac{3}{10} = \frac{6}{10} = \frac{3}{5} [/tex]
[tex] \frac{10}{10} - \frac{3}{10} = \frac{7}{10} [/tex]
b) mai mari cu = adunare
[tex] \frac{2}{9} + \frac{5}{9} = \frac{7}{9} [/tex]
[tex] \frac{2}{9} + \frac{7}{9} = \frac{9}{9} = 1 [/tex]
[tex] \frac{2}{9} + \frac{3}{9} = \frac{5}{9} [/tex]
[tex] \frac{2}{9} + \frac{6}{9} = \frac{8}{9} [/tex]
Explicație pas cu pas:
Bună !!
•Cerința :
~în atașament .
•Rezolvarea:
~mai jos.
[tex]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} [/tex]
[tex]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} [/tex]
^^Aceasta a fost rezolvarea exercițiului .^^
Sper sa fie de ajutor !!:)
***Succes la teme!!;)
