Explicație pas cu pas:

d) 4/9 + 1/3 = 4/9 + 3/9 = 7/9

f) (75/100 + 51/90 + 125/100)·100/33 =

= (3/4 + 17/30 + 5/4)·100/33 =

= (77/30)·(100/33) =

= 70/9

:[tex]\frac{4}{9}[/tex]+[tex]\frac{4}{3}[/tex]*[tex]\frac{2}{8}[/tex]=[tex]\frac{4}{9}[/tex]+[tex]\frac{12}{9}[/tex]*[tex]\frac{2}{8}[/tex]=[tex]\frac{16}{9}[/tex]*[tex]\frac{2}{8}[/tex]=[tex]\frac{16*2}{9*8}[/tex]=[tex]\frac{32}{72}[/tex]=[tex]\frac{16}{36}[/tex]=[tex]\frac{4}{9}[/tex]

(0,75+0,5(6)+1,25)*3,(03)=(3,75+1,25)*3,(03)=5*3,(03)=45

Succes!!!
