1,25=[tex] \frac{125}{100} [/tex] = [tex] \frac{5}{4} [/tex]
0,5=[tex] \frac{5}{10} [/tex] = [tex] \frac{1}{2} [/tex]
[tex] \frac{5}{4} [/tex] - [tex] \frac{1}{2} [/tex] : 2=
facem prima cu a 2-a inversata:
[tex] \frac{5}{4} [/tex] - [tex] \frac{1}{2} [/tex] x [tex] \frac{1}{2} [/tex] =
[tex] \frac{5}{4} [/tex] - [tex] \frac{1}{4} [/tex] = [tex] \frac{4}{4} [/tex]
= 1
Sper ca te-am ajutat
